注意题目中的这句话he put the strawberries on the cake randomly one by one,第一次选择草莓其实有N个可能,以某一个草莓为开头,然后顺序的随机摆放,所以最后的概率为n/m^(n-1),最后通过大数模板搞定该题的化简. C++代码 #include<iostream> #include<cstring> #include<cstdio> #include<iomanip> #include<algori…
int main(){ == key int m; while ( l <= r ) { m = ( l + r ) >> 1; if ( x[m] == key ) return m; else if ( key > x[m] ) l = m + 1; else r = m - 1; } >= key 中最小的 int ret; while ( l <= r ) { m = ( l + r ) >> 1; if ( x[m] >= key ) { r…
C++算法板子 高精度 高精度推荐用python来写,python有大整数,这里写的是关于C++的高精度运算模板 1.高精 * 低精 #include <iostream> #include <vector> using namespace std; vector<int> mul ( vector<int> A, int b ) { vector<int> C; // 结果按位存到 C 中 int t = 0; // 存放进位的数 for (…
Function1 Problem:F Time Limit:1000ms Memory Limit:65535K Description You know that huicpc0838 has been reviewing his textbooks and doing related exercises for the coming PG exams these days. One day, when he was abused by the sixth chapter of the te…
Problem Description Oneof the first users of BIT's new supercomputer was Chip Diller. He extended hisexploration of powers of 3 to go from 0 to 333 and he explored taking varioussums of those numbers. ``This supercomputer is great,'' remarked Chip.…
