Nov 8, 2023 · 该篇文章介绍了一个关于塔高度调整的问题，通过删除部分塔并应用加减一或除以二的操作，目标是找到最少的操作次数，文章详细描述了解决方案，利用set记录可能的高度和优化算法求解。 题意： n座塔，有各自高度，首先必须选择m座塔删除，然后对于剩余的塔执行三种操作之一。 1.使某座塔高度+1. 2.使某座塔高度-1. 3.某座塔高度 除以 2. 问最少操作多少次？ 解析： 首先，答案的高度一定是某座塔的高度，或者某座塔不断除以 2 经过的高度. set 记录所有塔高 …

Dec 2, 2022 · 对于一个可能的终值，我们可以求解把原数组中的每个数向终值靠拢需要的最小步数，然后对最小步数进行排序取前 n-m n −m 小的求和。 枚举所有可能的终值分别求解取最小值就是最终的答案。 这样写是 O (n^2log^2n) O(n2log2n) 的，会 TLE，容易发现我们第一部分求出的可能的终值有很多重复，去重即可 AC。 int T,n,m; using LL= long long; const int N= 501; int mid[N* 30 + 5]; LL solve() { LL ans= 1e18,sum,cnt,z= 0; scanf ("%d%d",&n,&m); int tot= 1; for (int i= …

Dec 15, 2022 · 本文探讨了一个关于调整不同高度积木塔的问题，目的是通过有限的操作使剩余的塔高度一致。 介绍了问题背景、操作规则，并提供了一种枚举所有可能值的解决方案。 摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 > Problem - A - Codeforces. 彭教授建造了n个不同高度的积木塔。 第i座塔的高度为 ai。 寿教授不喜欢这些塔，因为它们的高度是任意的。 他决定首先精确地移除其中的m个，然后执行以下一些（或不执行）操作。 选择一座塔，将其 …

An A Tower (German: A-Turm) was a standard type of communication tower that was built in all provinces (Bezirke) of East Germany during the 1950s. These towers were 25 metres high, their roofs were equipped with a host of antennas and were …
