Find Square Root under Modulo p | Set 2 (Shanks Tonelli algorithm) | 01 Apr, 2021
Given a number ‘n’ and a prime ‘p’, find square root of n under modulo p if it exists. Examples:
Input: n = 2, p = 113
Output: 62
62^2 = 3844 and 3844 % 113 = 2
Input: n = 2, p = 7
Output: 3 or 4
3 and 4 both are square roots of 2 under modulo
7 because (3*3) % 7 = 2 and (4*4) % 7 = 2
