Your task is to calculate ab mod 1337 where a is a positive integer and b is an extremely large positive integer given in the form of an array. Example1: a = 2 b = [3] Result: 8 Example2: a = 2 b = [1,0] Result: 1024 Credits:Special thanks to @Stomac…

题目描述: superPow(int a, int[] b),b是一个int数组,每个元素都是正的个位数,组合起来表示一个正整数,例如b=[1,2,3]表示123,求解a^b mod 1337. 思路描述: 本题的难点是当a和b足够大时会造成溢出,因此应考虑其他算法来实现. 理论支持(转幂算法): (a^b) mod c = ((a mod c)^b) mod c ----公式1 (x*y) mod c = ((x mod c) * (y mod c)) mod c  :积的取余等于取余的积的取…

50. Pow(x, n) 372. Super Pow https://www.cnblogs.com/grandyang/p/5651982.html https://www.jianshu.com/p/b256bd531df0 做这个题之间先了解两个公式: 公式一:a^b mod c = (a mod c)^b mod c公式二:(ab) mod c = (a mod c)(b mod c) mod c 这道题题让我们求一个数的很大的次方对1337取余的值,即a^b mod 1337.输入…

Implement pow(x, n), which calculates x raised to the power n(xn). Example 1: Input: 2.00000, 10 Output: 1024.00000 Example 2: Input: 2.10000, 3 Output: 9.26100 Example 3: Input: 2.00000, -2 Output: 0.25000 Explanation: 2-2 = 1/22 = 1/4 = 0.25 Note:…
