12 mod 1

Modulo p operation Given a positive integer p, any integer n must have an equation           n = kp + r Where K and R are integers and 0 ≤ r For positive integers p and integers A and B, the following operations are defined: Modulo operation: A

A ^ B mod C Assume 0 1. The original method is to first obtain a ^ B and finally mod C. However, this method is inefficient, and the time complexity is O (B), and a ^ B must be less than N to avoid overflow. It has great limitations.   2.

The beauty of the original root G of the modulo prime p is reflected in the presence of a non-zero number G power of each modulo p. Therefore, for any number 1 G, G ^ 2, G ^ 2, ''', G ^ (P-2), G ^ (pm) Exactly the same as model a P. The

1. Residual: The remainder after the division is divided, for example: MOD 4 = 2;   -17 MOD 4 =-1;    -3 MOD 4 =-3;    4 MOD (-3) = 1; -4 MOD 3 =-1; If a mod B is an XOR, then the resulting symbol is the same as a; Of course, a mod B is equivalent
