`Each vertex is a unique number in the range [0,${data[0]}].`,

`The next element of the data represents the edges of the graph.`,
`Two vertices u,v in a graph are said to be adjacent if there exists an edge [u,v].`,
`Note that the graph is undirected, meaning an edge [u,v] is the same as an edge [v,u].`,
`Note that an edge [u,v] is the same as an edge [v,u], as order does not matter.`,
`You must construct a 2-coloring of the graph, meaning that you have to assign each`,
`vertex in the graph a "color", either 0 or 1, such that no two adjacent vertices have`,
`the same color. Submit your answer in the form of an array, where element i`,
`represents the color of vertex i. If it is impossible to construct a 2-coloring of`,
`the given graph, instead submit an empty array.\n\n`,
