Tideman Solution: Cs50

The CS50 Tideman solution implements a voting system that determines the winner of an election based on ranked ballots. The solution involves reading input, initializing data structures, counting first-place votes, checking for a winner, eliminating candidates, and recounting votes. The implementation includes test cases to verify its correctness.

The ranks array holds the order of candidates for the current voter. For 3 candidates, if a voter ranks Alice (index 0) first and Bob (index 1) second, then ranks[0] = 0 and ranks[1] = 1 .

After locking:

Winner: Bob Ranked Candidates: ['Bob', 'Alice', 'Charlie']

Logic : Iterate through each candidate and check the locked matrix. If there is no candidate Cs50 Tideman Solution

# Rank candidates by win count ranked_candidates = sorted(candidates, key=lambda x: win_counts[x], reverse=True)

If the cycle is detected, do not lock. If the path ends without hitting the target, lock it in. The CS50 Tideman solution implements a voting system

// Function to read input void read_input(int *voters, int *candidates, voter_t **voters_prefs) // Read in the number of voters and candidates scanf("%d %d", voters, candidates);

Count how many voters preferred candidate A over candidate B for every possible pair. The ranks array holds the order of candidates

This post will break down the problem, explain the logic of the locked array, and give you a clean, working solution with an explanation you can actually understand.

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