Two errors: First, On lines 45-46, you have
what this loop does is copy the vector to a new variable
i
and clear the contents ofi
. To modify the actual adj vector you needSecond, on line 49 you initialize
edges
to sizem + 1
, but then in your for loop you push back (x, y) pairs to the end of the vector, so now you have an edge vector of length2m + 1
and when you iterate over all the edges at the end, you always include an edge pair (0, 0) which isn't right.Fixing those two errors gets AC.
