Tideman Solution — Cs50

pair pairs[MAX * (MAX - 1) / 2];

The first step is to record voter preferences. We use a 2D array, preferences[i][j] Cs50 Tideman Solution

This is the computationally complex aspect of the solution. The algorithm must create a directed graph by locking pairs one by one. pair pairs[MAX * (MAX - 1) / 2];

The Tideman solution involves the following steps: Bob beats Charlie

So to check if locking (winner, loser) is safe:

Then came the hardest part: . Alex had to draw arrows from winners to losers. But there was a curse—if an arrow created a "cycle" (where Alice beats Bob, Bob beats Charlie, and Charlie beats Alice), the arrow could not be drawn.
