Solution [2021] — Cs50 Tideman

Iterate through every candidate. If locked[j][i] is false for all candidates j , then i is the winner. They are undefeated.

// Structure to represent a voter typedef struct voter int *preferences; voter_t; Cs50 Tideman Solution

: Iterates through the sorted pairs and attempts to add them to a directed graph ( locked[i][j] = true Cycle Detection Iterate through every candidate

My first instinct was to use a simple sorting algorithm (like bubble sort) on the pairs array. But I kept getting the order wrong. I was trying to sort the candidates themselves, rather than the magnitude of the margin . Cs50 Tideman Solution

The algorithm follows three main phases to determine a winner:
