http://poj.org/problem?id=2115 题意: 给你一个变量,变量初始值a,终止值b,每循环一遍加c,问一共循环几遍终止,结果mod2^k.如果无法终止则输出FOREVER. 思路: 根据题意原题可化成c * x = b - a mod (2 ^ k),然后解这个模线性方程. #include<iostream> #include<algorithm> #include<cstring> #include<cstdio> #includ…
Description The modular modular multiplicative inverse of an integer a modulo m is an integer x such that a-1≡x (mod m). This is equivalent toax≡1 (mod m). Input There are multiple test cases. The first line of input is an integer T ≍ 2000 indicating…
