Case 1:
dist[s --> t] > d; NO.
Case 2:
dist[s --> t] === d (mod 2); YES, since just repeat an edge.
Case 3:
dist[s --> t] is different.
Path will look like s --> k --> k --> t, where k --> k completes odd cycle.
Another way to think about it?
If there is a path of length N and a path of length N + 1 % 2
For each node is it possible to compute shortest even and odd paths?
Keep array[5000][5000][2] with modified bfs maybe?
1 million * N is too slow (5 billion) so need to precompute more.
m <= 5000???
Find odd cycles
