WebWe need to use math and formal logic to prove an algorithm works correctly. A common proof technique is called "induction" (or "proof by loop invariant" when talking about algorithms). Induction works by showing that if a statement is true given an input, it must also be true for the next largest input.

WebA truth table is a graphical representation of the possible combinations of inputs and outputs for a Boolean function or logical expression. It lists all of the possible combinations of input values (usually represented as 0 and 1) and shows the corresponding output value for each combination.
