You are given a sequence of integers of length nn and integer number kk. You should print any integer number xx in the range of [1;109][1;109] (i.e. 1≤x≤1091≤x≤109) such that exactly kk elements of given sequence are less than or equal to xx. Note th…
题目大意:有n座塔,塔高h[i],每次给定高度H对他们进行削切,要求每次削掉的所有格子数不能超过k个,输出最少削几次才能使所有塔的高度相同. 思路一:差分+贪心 对于每一个高度h,用一个数组让1~h的数,每一个都加一.用差分求一下后缀和可以完成. AC code: #include<bits/stdc++.h> using namespace std; typedef long long ll; ; ll arr[N]; int main() { ll n,k; cin>>n>…
