WebSep 20, 2016 · This proof is a proof by induction, and goes as follows: P (n) is the assertion that "Quicksort correctly sorts every input array of length n." Base case: every input array of length 1 is already sorted (P (1) holds) Inductive step: fix n => 2. Fix some input array of length n. Need to show: if P (k) holds for all k < n, then P (n) holds as well WebIn calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms.
