The complete Tideman solution successfully simulates an election where the strongest preferences are honored without creating logical loops. The result is a system that identifies the most broadly preferred candidate by prioritizing majorities and maintaining a stable, acyclic hierarchy of winners. needed for the lock_pairs cycle check? (CS50) TIDEMAN - PROBLEM SET 3 | SOLUTION
Check C→A: Start = C (loser), end = A (winner). Path? B→C? No, C→ nothing. Actually: Wait — We check from loser (C) to winner (A). DFS from C: C→? No outgoing in locked yet. So no path. Lock it? But locking C→A would create A→B→C→A (cycle). Let’s trace: Cs50 Tideman Solution
if (locked[from][i] && can_reach(i, target)) return true; target)) return true
