不考虑取模的快速幂运算(迭代法) /* Iterative Function to calculate (x^y) in O(logy) */int power(int x, unsigned int y){int res = 1; // Initialize resultwhile (y > 0){// If y is odd, multiply x with resultif (
问题描述: 给定一个包含小数点的在0.0到99.999的包含6位的输入数 r(以字符串的形式),和一个在0到25之间的数 n, 求 r 的 n 次方,要求是,输出结果不包括无效的0,这里的0既包括了在所得结果的最后几位的无效的0,也包括了0.345....中的0,即结果应当是.345....的形式,当所得结果是一个整数时,不应当打印小数点。 这是一个高精度计算的问题,思路是通过模
