Shifting nth root algorithm not useful for computing roots with a computer, as it is always outperformed by much simpler binary search, and has the same memory complexity. 1. 0 1 1 0 1 1. 7 3 2 0 5 1. 7 0 9 9 7 1. 6 2 6 5 7 Shifting nth root algorithm The shifting "n"th root algorithm is an algorithm for extracting the "n"th root of a positive real number which proceeds iteratively by shifting in "n" digits of the radicand, starting with the most significant, and produces one digit of the root on each iteration, in a manner similar
Digital root number's additive persistence; in the above example, the additive persistence of 65,536 is 2. It helps to see the digital root of a positive integer as the position it holds with respect to the largest multiple of 9 less than the number itself. For example, the digital root of 11 is 2, which means that 11 is the second number after 9. Likewise, the digital root of 2035 is 1, which means that 2035 − 1 is a multiple of 9. If a number produces a digital root of exactly 9, then the number is a multiple of 9. With
