In yesterday's Div 3 contest in problem D, I used unordered_map to store elements, thinking it would be faster, but someone cracked my code, and my friend who had almost the same code, but used map instead of unordered_map, could not be cracked. Why was my code hacked, because unordered_map is faster than map, right? ↵
