Correct Solution:
```
n, m = [int(i) for i in input().split()]
n += 1 # one-indexed
A = [[int(i) for i in input().split()] for j in range(m)]
m += 1
def check(upper):
p = [[] for i in range(n)]
d = [0] * n #record num of parents
for u, v in A[:upper]:
p[u].append(v) ... | output | 1 | 108,266 | 14 | 216,533 |
