#Atcoder

Security 2 (ABC 407 C)

My solution approach to a cool atcoder problem about a unique pass-code device with 2 distinct operations. The solution is complemented by an interactive visualization that brings the device and its mechanics to life.

Domino Covering XOR (ABC 407 D)

AtCoder's Domino Covering XOR problem solved using bit manipulation. The solution represents domino coverings as bitmasks to do an exhaustive search in order to get the maximum XOR value.
