题目# C. Make Equal With Mod time limit per test:2 seconds memory limit per test:256 megabytes input:standard input output:standard output You are given an array of n non-negative integers a1,a2,…,an. You can make the following operation: choose an integer x≥2x≥2 and replace each n...
CodeForces 1188D Make Equal DP dp[bit][j]填完了bit位之后,产生进位的状态是j,所需的最小花费。 若j以二进制(0010010..)的第i位表示第i个数是否发生进位,则j的状态有1<<n个; 假设结束时所有数均为X,考虑每个数第bit位是否有进位,即在模 1 << (bit + 1) 下 a[i] >= X是否满足。 由此...
Codeforces 1154B Make Them Equal 题目链接:http://codeforces.com/problemset/problem/1154/B 题意:给定数组,可以给任意的的元素加上D 或者 减去D,如果能 使数组元素都相等,输出最小的D,不能输出-1。 思路:若要相等,唯有种类数小于3的才可以。 AC代码: 1#include<bits/stdc++.h>2usingnamespacestd;3int...

For each test case, output one integer — the minimum number of burles that will have to be spent to make all the elements of the array equal. It can be shown that this can always be done. Input The first line contains a single integer tt (1≤t≤1041≤t≤104)— the number of inp...
Clearly, they all need to become equal to Sum/N, but the hard part is determining whether it is possible or not. I was trying to do this with a while loop but it is getting really slow when I try for large numbers. Sorry if this is a really silly question but I would appreciate ...
标题Codeforces Round #629 (Div. 3)F. Make k Equal (前后缀和+讨论) 下图来自某博客园大佬,我认为写的很赞。 下面是AC代码 #include<bits/stdc++.h> using namespace std; typedef long long ll; const ll N=2e5+5,inf=1e15; ll a[N],n,k,pre[N],suf[N],ans=inf; ...
Codeforces Round 673 (Div. 1) B. Make Them Equal bhdtr Warframe高手 3 人赞同了该文章 Problem - B - Codeforcescodeforces.com/contest/1416/problem/B 好巧妙的做法。 题意: 给定一个长度为 n 的数组,第 i 个数的大小为 a[i],每次操作你可以选定 i, j, x 使得,a[i] = a[i] - i ...
