Polynomial time turing machine

WebBy the definition of P, we know that there exists a polynomial-time algorithm that decides L, so we can construct a Turing machine that decides L in time O(p(n)) for all n. Then, we can set k(n) to be some polynomial that is greater than or equal to p(n) for all n, and simulate the Turing machine for k(n) steps on inputs of length n.
