题目链接:http://codeforces.com/problemset/problem/379/C 题目意思:有n个users,每个user都有自己想升的rating.要解决的问题是给予每个人不同的rating,使得每个人rating不比他期望的rating小,即 安排的rating >= 他自己的希望的rating,还有一个条件就是 总rating之和要最小. 要想使得总rating最少,那么安排的rating要尽可能小.把rating从小到大排序.对最小的rating值当然就给予这个值,…

https://www.luogu.org/problemnew/show/CF379C 一道水题,折腾了我好久! 解题: 先排序,从小到大挨个满足客户,把最终rating放进集合里,判断是否已经给出,如果这个期望rating已经存在,那么取集合里最大的rating+1,既要满足期望,又不能重复,从小到大排序,每次取最大+1: #include<stdio.h> #include<math.h> #include<string.h> #include<algori…

http://codeforces.com/contest/379/problem/C 思路:先排序,然后判断如果rating>ans,ans=rating否则ans++;然后对应的位置输出就可以: #include <cstdio> #include <cstring> #include <map> #include <algorithm> #define LL __int64 #define maxn 500010 using namespace…

Java has won the TIOBE Index programming language award of the year. This is because Java has the largest increase in popularity in one year time (+5.94%). Java leaves runner ups Visual Basic.NET (+1.51%) and Python (+1.24%) far behind. At first sigh…

There is hardly any doubt about it, Java will become TIOBE's programming language of the year 2015. The steep fall of Objective-C of almost 8% this year seems to be completely absorbed by the most popular language at the moment. More about Java next…

坏味道--发散式变化(Divergent Change) 发散式变化(Divergent Change) 类似于 霰弹式修改(Shotgun Surgery) ,但实际上完全不同.发散式变化(Divergent Change) 是指一个类受多种变化的影响.霰弹式修改(Shotgun Surgery) 是指多种变化引发多个类相应的修改. 特征 你发现你想要修改一个函数,却必须要同时修改许多不相关的函数.例如,当你想要添加一个新的产品类型时,你需要同步修改对产品进行查找.显示.排序的函数. 问题原因…

原本想着在<input>输入输入框中添加change事件,来实现对输入内容的限定. 当人们在使用时跟多的会直接去点击完成.所以完成按钮的点击事件会和change事件产生 冲突,所以我把验证放在了完成按钮中.这样会出现一个问题, input输入框的原值我无法拿到,在用户输入负值,和0之后我这边能做的只能是提醒, 不能把原值返回.但是用户应该是知道自己想要多少的,所以我暂时没有管他..…
