The difference between Algorithm A and Algorithm B are analogous to the differences between linear search and binary search. Algorithm A and linear search only reduce the size of their problem by 1 after each iteration/recursion. jan nohling photographyWebJan 3, 2024 · 1. Integer fast power. The normal operation is to multiply the value of x one by one, and the multiplication operation runs 7 times. You can also use this method of operation, first multiply to get x^2, and then multiply x^2 three times. This is obviously faster than the first case. So for the fast powers of integers, this idea is also combined. lowest recorded healthy heart rate
