Hello codeforces, I'v recently been struggling with this problem Xor-MST.In it's tutorial it says u should use Boruvka's algorithm. For sake of learning i'v been trying to solve it using prim's algorithm but it runs out of time. I was wondering if it's some inefficiency in my coding or it's the algorithm which can't solve the problem in given time? here is my last code submitted: MY CODE thanks in advance.
