Web27 apr. 2024 · So to calculate n! modulo p for p ≥ 2 we take the following steps: Step 1: Find the smallest prime factor q of p. If n ≥ q then the result is 0. Step 2: Let x = 1, then for 1 ≤ i ≤ n replace x with (x * i) modulo p, and x is the result.

We don’t measure the speed of an algorithm in seconds (or minutes!). Instead, we measure the number of operations it takes to complete. The O is short for “Order of”. So, if we’re discussing an algorithm with O (n), we say its order of, or ...
