This document contains code to implement bit stuffing and byte stuffing. For bit stuffing, it takes in a binary frame as input, inserts 0s whenever there are 5 consecutive 1s, and outputs the stuffed frame. For byte stuffing, it takes in a string frame, inserts "esc" before strings that equal "flag" or "esc", and outputs the stuffed frame. The aim was to compile and execute these implementations, which was successful as per the results.
