Given a connected undirected graph with $n$ nodes and $m$ edges, and two distinct nodes $a$ and $b$, count unordered pairs $(u, v)$ where $u < v$ such that: $u \neq a$, $u \neq b$, $v \neq a$, $v \neq b$ Every path from $u$ to $v$ passes through both $a$ and $b$ Approach The solution involves ide...

Problem: Find Champion I In a tournament with n teams, numbered from 0 to n - 1, you are given a square boolean matrix grid of size n x n. For all pairs (i, j) where 0 <= i, j <= n - 1 and i != j, if grid[i][j] == 1, then team i is stronger than team j. Otherwise, team j is stronger than team...
