Codewriting

Given an undirected graph graph that is represented by its adjacency matrix, return whether or not it is possible to add no more than two edges to this graph in order to make all the degrees of nodes even. Keep in mind that in the resulting graph there should be at most one edge between any pair of nodes.

Example

• For

graph = [[false, true, false, false],
         [true, false, true, false],
         [false, true, false, true],
         [false, false, true, false]]

the output should be

solution(graph) = true.
