Extracted text: We are going to write a Turing machine that reads a string of 1's as input and produces a 1 for output if the string is a length that is a multiple of 3 and outputs a O otherwise. The 1 or O should be spaced 1 position to the right of the end of the input. You may assume that the input contains only zero or more 1's. For example here are four before and after snapshots.
