WebI've done the optimizations but still TLE, it turned out switching from vector> seen(7, vector(7, false)); to bool seen[7] [7]; memset(seen, false, sizeof(seen)); Made the difference from TLE on 5 testcases (including all '?') to getting AC. This sucks because I hate memset :P → Reply adityanand09 6 months ago, # ← Rev. 2 → 0
