Codeforces Round #372 (Div. 2) 不知不觉自己怎么变的这么水了,几百年前做A.B的水平,现在依旧停留在A.B水平.甚至B题还不会做.难道是带着一种功利性的态度患得患失?总共才打的几场 CF 节节掉分.学了快一年了成了个水货. 废话就不多说了,来看这次的这两题吧.很多CF的题是不想写博客的,如果题目质量很好的话我倒是愿意留在我的博客里: A. Crazy Computer time limit per test 2 seconds memory limit per te…

题目链接:http://codeforces.com/problemset/problem/716/A 题目大意: 输入 n c, 第二行 n 个整数,c表示时间间隔 秒. 每个整数代表是第几秒.如果本次和下一秒间隔>c 则之前的计数次数清0,否则每次输入一个数,计数++: 问最后剩几个数. 举例: input: 6 51 3 8 14 19 20 output: 3 解析: 1 3 8 此时剩 3 个数,因为每次输入距离下次输入时间间隔都<5.下一次是 14 距离上一次 间隔为14-8>…

Content 有一个电脑,如果过了 \(c\) 秒之后还没有任何打字符的操作,就把屏幕上面所有的字符清空.现在,给定 \(n\) 次打字符的时间 \(t_1,t_2,...,t_n\),求最后屏幕剩下的字符数. 数据范围:\(1\leqslant n\leqslant 10^5,1\leqslant c\leqslant 10^9,1\leqslant t_1\leqslant t_2\leqslant t_3\leqslant ...\leqslant t_n\leqslant 10^9\)…

题意: 思路: Codeforces Round #370(Solved: 4 out of 5) A - Memory and Crow 题意:有一个序列,然后对每一个进行ai = bi - bi + 1 + bi + 2 - bi + 3.... 的操作,最后得到了a 序列,给定 a 序列,求原序列. 思路:水. #include <set> #include <map> #include <stack> #include <queue> #includ…

用了两场比赛上Div 1感觉自己好腊鸡的说...以下是这两场比赛的部分题解(不得不说有个黄学长来抱大腿还是非常爽的) Round #372 : Div 2 A:Crazy Computer 题意:给定N个输入和一个时间长度M,每次输入屏幕上增加一个字符,若两个输入间隔大于M则屏幕上的字符会被清空,问结束时屏幕上还有多少个字符 直接模拟没有什么好说的 代码: #include<cstdio> #include<iostream> #include<cstring> #in…
