Proving Algorithm Correctness

proof by cases/enumeration proof by chain of i s proof by contradiction proof by contrapositive For any algorithm, we must prove that it always returns the desired output for all legal instances of the problem. For sorting, this means even if the input is already sorted or it contains repeated elements. Proof by Counterexample
