COMPUTER SCIENCE -- THEORY OF COMPUTATION Please write a Turing-machine style of algorithm to decide the language L1 given below. Use specific, precise, step-by-step English. Describe how to test whether or not an input string is in the language L1 in finite time. A state diagram is not necessary at all -- but optional and helpful. L1 = {w : every ‘a’ within w is to the left of every ‘b’ within w} over the following alphabet Σ = {a,...
