I find vicarious ways to find square root in binary search,
for example, a standard solution:
def mySqrt(self, x: int) -> int:
if x <= 1:
return x
lo, hi = 0, x
while lo <= hi:
mid = (lo + hi) // 2
if mid ** 2 <= x < (mid + 1) ** 2:

I wrote a code to calculate the lengths of strongly connected components in a graph. The results I get are correct but it scales horribly.
