Coding Contracts
|
|
================
|
|
Coding Contracts are a mechanic that lets players earn rewards in
|
|
exchange for solving programming problems.
|
|
|
|
Coding Contracts are files with the ".cct" extensions. They can
|
|
be accessed through the :ref:`terminal` or through scripts using
|
|
the `Coding Contract API <https://github.com/danielyxie/bitburner/blob/dev/markdown/bitburner.codingcontract.md>`_
|
|
|
|
Each contract has a limited number of attempts. If you
|
|
provide the wrong answer too many times and exceed the
|
|
number of attempts, the contract will self destruct (delete itself)
|
|
|
|
Currently, Coding Contracts are randomly generated and
|
|
spawned over time. They can appear on any server (including your
|
|
home computer), except for your purchased servers.
|
|
|
|
|
|
Running in Terminal
|
|
^^^^^^^^^^^^^^^^^^^
|
|
To run a Coding Contract in the Terminal, simply use the
|
|
:ref:`run_terminal_command` command::
|
|
|
|
$ run some-contract.cct
|
|
|
|
Doing this will bring up a popup. The popup will display
|
|
the contract's problem, the number of attempts remaining, and
|
|
an area to provide an answer.
|
|
|
|
Interacting through Scripts
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
See the `Coding Contract API <https://github.com/danielyxie/bitburner/blob/dev/markdown/bitburner.codingcontract.md>`_.
|
|
|
|
Submitting Solutions
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
Different contract problem types will require different types of
|
|
solutions. Some may be numbers, others may be strings or arrays.
|
|
If a contract asks for a specific solution format, then
|
|
use that. Otherwise, follow these rules when submitting solutions:
|
|
|
|
* String-type solutions should **not** have quotation marks surrounding
|
|
the string (unless specifically asked for). Only quotation
|
|
marks that are part of the actual string solution should be included.
|
|
* Array-type solutions should be submitted with each element
|
|
in the array separated by commas. Brackets are optional. For example,
|
|
both of the following are valid solution formats::
|
|
|
|
1,2,3
|
|
[1,2,3]
|
|
|
|
However, if the solution is a multidimensional array, then
|
|
all arrays that are not the outer-most array DO require the brackets.
|
|
For example, an array of arrays can be submitted as one of the following::
|
|
|
|
[1,2],[3,4]
|
|
[[1,2],[3,4]]
|
|
|
|
* Numeric solutions should be submitted normally, as expected
|
|
|
|
Rewards
|
|
^^^^^^^
|
|
There are currently four possible rewards for solving a Coding Contract:
|
|
|
|
* Faction Reputation for a specific Faction
|
|
* Faction Reputation for all Factions that you are a member of
|
|
* Company reputation for a specific Company
|
|
* Money
|
|
|
|
The 'amount' of reward varies based on the difficulty of the problem
|
|
posed by the Coding Contract. There is no way to know what a
|
|
Coding Contract's exact reward will be until it is solved.
|
|
|
|
Notes
|
|
^^^^^
|
|
|
|
* The *scp* Terminal command does not work on Coding Contracts
|
|
|
|
List of all Problem Types
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The following is a list of all of the problem types that a Coding Contract can contain.
|
|
The list contains the name of (i.e. the value returned by
|
|
:js:func:`getContractType`) and a brief summary of the problem it poses.
|
|
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Name | Problem Summary |
|
|
+====================================+==========================================================================================+
|
|
| Find Largest Prime Factor | | Given a number, find its largest prime factor. A prime factor |
|
|
| | | is a factor that is a prime number. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Subarray with Maximum Sum | | Given an array of integers, find the contiguous subarray (containing |
|
|
| | | at least one number) which has the largest sum and return that sum. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Total Ways to Sum | | Given a number, how many different ways can that number be written as |
|
|
| | | a sum of at least two positive integers? |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Total Ways to Sum II | | You are given an array with two elements. The first element is an integer n. |
|
|
| | | The second element is an array of numbers representing set of available integers. |
|
|
| | | How many different ways can that number n be written as |
|
|
| | | a sum of integers containing in a given set? |
|
|
| | | You can use same integer from a set infinitely many times. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Spiralize Matrix | | Given an array of array of numbers representing a 2D matrix, return the |
|
|
| | | elements of that matrix in clockwise spiral order. |
|
|
| | | |
|
|
| | | Example: The spiral order of |
|
|
| | | |
|
|
| | | [1, 2, 3, 4] |
|
|
| | | [5, 6, 7, 8] |
|
|
| | | [9, 10, 11, 12] |
|
|
| | | |
|
|
| | | is [1, 2, 3, 4, 8, 12, 11, 10, 9, 5, 6, 7] |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Array Jumping Game | | You are given an array of integers where each element represents the |
|
|
| | | maximum possible jump distance from that position. For example, if you |
|
|
| | | are at position i and your maximum jump length is n, then you can jump |
|
|
| | | to any position from i to i+n. |
|
|
| | | |
|
|
| | | Assuming you are initially positioned at the start of the array, determine |
|
|
| | | whether you are able to reach the last index of the array. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Merge Overlapping Intervals | | Given an array of intervals, merge all overlapping intervals. An interval |
|
|
| | | is an array with two numbers, where the first number is always less than |
|
|
| | | the second (e.g. [1, 5]). |
|
|
| | | |
|
|
| | | The intervals must be returned in ASCENDING order. |
|
|
| | | |
|
|
| | | Example: |
|
|
| | | [[1, 3], [8, 10], [2, 6], [10, 16]] |
|
|
| | | merges into [[1, 6], [8, 16]] |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Generate IP Addresses | | Given a string containing only digits, return an array with all possible |
|
|
| | | valid IP address combinations that can be created from the string. |
|
|
| | | |
|
|
| | | An octet in the IP address cannot begin with '0' unless the number itself |
|
|
| | | is actually 0. For example, "192.168.010.1" is NOT a valid IP. |
|
|
| | | |
|
|
| | | Examples: |
|
|
| | | 25525511135 -> [255.255.11.135, 255.255.111.35] |
|
|
| | | 1938718066 -> [193.87.180.66] |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Algorithmic Stock Trader I | | You are given an array of numbers representing stock prices, where the |
|
|
| | | i-th element represents the stock price on day i. |
|
|
| | | |
|
|
| | | Determine the maximum possible profit you can earn using at most one |
|
|
| | | transaction (i.e. you can buy an sell the stock once). If no profit |
|
|
| | | can be made, then the answer should be 0. Note that you must buy the stock |
|
|
| | | before you can sell it. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Algorithmic Stock Trader II | | You are given an array of numbers representing stock prices, where the |

|
|
| | | |
|
|
| | | Determine the maximum possible profit you can earn using as many transactions |
|
|
| | | as you'd like. A transaction is defined as buying and then selling one |
|
|
| | | share of the stock. Note that you cannot engage in multiple transactions at |
|
|
| | | once. In other words, you must sell the stock before you buy it again. If no |
|
|
| | | profit can be made, then the answer should be 0. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Algorithmic Stock Trader III | | You are given an array of numbers representing stock prices, where the |

|
|
| | | |
|
|
| | | Determine the maximum possible profit you can earn using at most two |
|
|
| | | transactions. A transaction is defined as buying and then selling one share |
|
|
| | | of the stock. Note that you cannot engage in multiple transactions at once. |
|
|
| | | In other words, you must sell the stock before you buy it again. If no profit |
|
|
| | | can be made, then the answer should be 0. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Algorithmic Stock Trader IV | | You are given an array with two elements. The first element is an integer k. |
|
|
| | | The second element is an array of numbers representing stock prices, where the |
|
|
| | | i-th element represents the stock price on day i. |
|
|
| | | |
|
|
| | | Determine the maximum possible profit you can earn using at most k transactions. |
|
|
| | | A transaction is defined as buying and then selling one share of the stock. |
|
|
| | | Note that you cannot engage in multiple transactions at once. In other words, |
|
|
| | | you must sell the stock before you can buy it. If no profit can be made, then |
|
|
| | | the answer should be 0. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Minimum Path Sum in a Triangle | | You are given a 2D array of numbers (array of array of numbers) that represents a |
|
|
| | | triangle (the first array has one element, and each array has one more element than |
|
|
| | | the one before it, forming a triangle). Find the minimum path sum from the top to the |
|
|
| | | bottom of the triangle. In each step of the path, you may only move to adjacent |
|
|
| | | numbers in the row below. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Unique Paths in a Grid I | | You are given an array with two numbers: [m, n]. These numbers represent a |
|
|
| | | m x n grid. Assume you are initially positioned in the top-left corner of that |
|
|
| | | grid and that you are trying to reach the bottom-right corner. On each step, |
|
|
| | | you may only move down or to the right. |
|
|
| | | |
|
|
| | |
|
|
| | | Determine how many unique paths there are from start to finish. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Unique Paths in a Grid II | | You are given a 2D array of numbers (array of array of numbers) representing |
|
|
| | | a grid. The 2D array contains 1's and 0's, where 1 represents an obstacle and |
|
|
| | |
|
|
| | | 0 represents a free space. |
|
|
| | | |
|
|
| | | Assume you are initially positioned in top-left corner of that grid and that you |
|
|
| | | are trying to reach the bottom-right corner. In each step, you may only move down |
|
|
| | | or to the right. Furthermore, you cannot move onto spaces which have obstacles. |
|
|
| | | |
|
|
| | | Determine how many unique paths there are from start to finish. |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Shortest Path in a Grid | | You are given a 2D array of numbers (array of array of numbers) representing |
|
|
| | | a grid. The 2D array contains 1's and 0's, where 1 represents an obstacle and |
|
|
| | | 0 represents a free space. |
|
|
| | | |
|
|
| | | Assume you are initially positioned in top-left corner of that grid and that you |
|
|
| | | are trying to reach the bottom-right corner. In each step, you may move to the up, |
|
|
| | | down, left or right. Furthermore, you cannot move onto spaces which have obstacles. |
|
|
| | | |
|
|
| | | Determine if paths exist from start to destination, and find the shortest one. |
|
|
| | | |
|
|
| | | Examples: |
|
|
| | | [[0,1,0,0,0], |
|
|
| | | [0,0,0,1,0]] -> "DRRURRD" |
|
|
| | | [[0,1], |
|
|
| | | [1,0]] -> "" |
|
|

+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Sanitize Parentheses in Expression | | Given a string with parentheses and letters, remove the minimum number of invalid |
|
|
| | | parentheses in order to validate the string. If there are multiple minimal ways |
|
|
| | | to validate the string, provide all of the possible results. |
|
|
| | | |
|
|
| | | The answer should be provided as an array of strings. If it is impossible to validate |
|
|
| | | the string, the result should be an array with only an empty string. |
|
|
| | | |
|
|
| | | Examples: |
|
|
| | | ()())() -> [()()(), (())()] |
|
|
| | | (a)())() -> [(a)()(), (a())()] |
|
|
| | | )( -> [""] |
|
|
+------------------------------------+------------------------------------------------------------------------------------------+
|
|
| Find All Valid Math Expressions | | You are given a string which contains only digits between 0 and 9 as well as a target |
|
|
| | | number. Return all possible ways you can add the +, -, and * operators to the string |
|
|
| | | of digits such that it evaluates to the target number. |
|
|
| | | |
|
|
| | | The answer should be provided as an array of strings containing the valid expressions. |
|
|
| | | |
|
|
| | | NOTE: Numbers in an expression cannot have leading 0's |
|
|
| | | NOTE: The order of evaluation expects script operator precedence |
|
|
| | | |
|
|
| | | Examples: |
|
|
| | | Input: digits = "123", target = 6 |
|
|
| | | Output: [1+2+3, 1*2*3] |
|
|
| | | |
|
|
| | | Input: digits = "105", target = 5 |
|
|
| | | Output: [1*0+5, 10-5] |
