Edu 165 C. Minimizing the Sum 三巷 来自专栏 · Codeforces题解 2 人赞同了该文章 题意: 有一种操作:选择数组中的一个元素,并用其邻近元素的值替换它。求经过k次操作数组累和的最小值。 Problem - C - Codeforces 题解: 教育场的题,特别是c题总是相对简单(ps:也可能是因为少怪题和近期写的少了的...

I think this was a problem in a codeforces or topcoder, but I cannot remember where. For example, if N = 5 and we have Array = [6, 1, 1, 1, 1], you can make them all equal to 2 in just four operations. Clearly, they all need to become equal to Sum/N, but the hard par...
Codeforces-1256-D. Binary String Minimizing(贪心) D. Binary String Minimizing You are given a binary string of length n (i. e. a string consisting of n characters ‘0’ and ‘1’). In one move you can swap two adjacent characters of the string. What is the lexicographically minimum ...
Outputis an array that has aminimum count of each element of N. We need to make some changes in original array to get the output such that cost is minimized. LetC(x, y)becostof changing numberxto numbery, thenC(x, y) = |x-y|. Our task is to minimize the total cost of chang...
The second line of the test case contains one string consisting of n characters '0' and '1'. It is guaranteed that the sum of n over all test cases does not exceed 106 (∑n≤106). Output For each test case, print the answer on it: the lexicographically minimum possible string of le...
Codeforces Round #598 (Div. 3), problem: © Platforms Jumping 题目大意 给你一段长度为n的二进制码 然后给你k次操作 使得字符串的字典序最小 题解 一开始考虑是让1移动 后面想了想既然是贪心的话 我们要逆向思维 直接移动0方便多了不是? 注意细节,我存储0的数组是从下标0开始的 因为第一个0最终位置...
