C. Partitioning the Array tyk 来自专栏 · 算法题解 3 人赞同了该文章 Problem - 1920C - Codeforcescodeforces.com/problemset/problem/1920/C 本题考察同余运算的性质。 首先从求两个数的同余入手(x和y),即:x%m==y%m。 由于他们的余数相同,所以变一下式子:x%m-y%m==

Devu being a small kid, likes to play a lot, but he only likes to play with arrays. While playing he came up with an interesting question which he could not solve, can you please solve it for him? Given an array consisting of distinct integers. Is it possible to partition the whole ...
partition the array into exactly K subarrays and calculate their sum. find the minimum possible difference of the maximum sum and the minimum sum. (1<k<=n<=40) for example for N=6 and K=3 and array={5 1 1 1 3 2} the optimal way is to split it into [5][1 1 1][3 2] so...
Given an array A of N (1 <= N <= 100,000) positive integers, is it possible to remove exactly two elements in the array in order to form a partition of the array into three contiguous subarrays with equal sums? For example, if A = [ ...
【Codeforces 1114B】Yet Another Array Partitioning Task,【链接】"我是链接,点我呀:)"【题意】让你把数组分成k个连续的部分使得每个部分最大的m个数字的和最大【题解】把原数组降序排序然后选取前mk个数字打标记然后对于原数组一直贪心地取直到这个区间选了m个打标记的

Codeforces 439C Devu and Partitioning of the Array(模拟) 题目链接:Codeforces 439C Devu and Partitioning of the Array 题目大意:给出n个数,要分成k份,每份有若干个数,可是仅仅须要关注该份的和为奇数还是偶数,要求偶数堆的个数为p。 输出方案。 解题思路:首先先将数组依照奇偶排序。也能够分开储存。
B. Yet Another Array Partitioning Task 题目链接:http://codeforces.com/contest/1114/problem/B 题面: 题目描述:给你一个n个数字的数组,要求把他划分为k块,每块的数字个数不少于m个,要求所有划分前m大的数字之和最大,输出和和划分的办法。 题目解法:很容易知道sort之后的数组取前m*k个数,之后划分再用...
