HDU5053the Sum of Cube(水题) 题目链接 题目大意:给你L到N的范围,要求你求这个范围内的全部整数的立方和. 解题思路:注意不要用int的数相乘赋值给longlong的数,会溢出. 代码: #include <cstdio> #include <cstring> const int N = 10005; typedef long long ll; ll t[N]; void init () { for (ll i = 1; i <= N - 5; i++…

You are given an array aa consisting of nn integers. In one move, you can choose two indices 1≤i,j≤n1≤i,j≤n such that i≠ji≠j and set ai:=ajai:=aj . You can perform such moves any number of times (possibly, zero). You can choose different indices in d…

1296A - Array with Odd Sum 题意:可以改变数组中的一个数的值成另外一个数组中的数,问能不能使数组的和是个奇数 思路:签到,如果本来数组的和就是个奇数,那就OK 如果不是,就需要把数组中其中一个奇(偶)数改成偶(奇)数,相当于加一减一 所以测一下这个数组如果有个奇数并且还有个偶数就行 #include <cstdio> #include <iostream> #include <map> #include <set> #include…

A. Array with Odd Sum Description You are given an array \(a\) consisting of \(n\) integers. In one move, you can choose two indices \(1 \le i, j \le n\) such that \(i \ne j\) and set \(a_i := a_j\). You can perform such moves any number of times (po…
