求a^b%c Descr iption Now you are given three positive integers a , b and c,please calculate a^b % c; Input The input contains a single test case,The first line contains three integers a , b and c (0 < a < 1000 , 0 < b < 1000000000 , 0 <
RSA算法中求模乘运算的结果 void modular exponentitation int x int r int p int t { int a b c; a x;b r;c t; if b 0 如果b为零 则结果等于1 { printf "%d" c ; 输出结果 return; } if b>0 && b%2 0 b为偶数 { b b 2; a a a %p; }
