I'll help you create a feature for CS50's Tideman problem. Since you didn't specify which feature, I'll suggest that shows how ties are resolved in the Tideman algorithm. Feature: Tie-Breaking Visualization This feature adds a function that visualizes how the Tideman algorithm resolves tied preferences and locked pairs, making it easier to debug and understand the election process. Code Implementation // Add this function to your tideman.c file // Structure to track tie information typedef struct { int winner; int loser; int margin; // margin of victory (votes_winner - votes_loser) bool is_tie; // whether this pair is tied } pair_info;
