AtCoder Grand Contest 010 A题 题目链接 题意 n个数,每次取两个奇偶性相同的数用他们的和代替他们,问最后能否只剩下一个数. 题解 因为奇偶相同的两个数之和一定是偶数,所以YES->sum是偶数. sum是偶数,那么一定是偶数个奇数加上任意个偶数,偶数个奇数两两合并一下就变成了偶数,n个偶数一定可以通过n-1次替代变成1个数.因此sum是偶数->YES. 代码 #include <cstdio> #include <cstring> #incl…

Assume you have an array of length n initialized with all 0's and are given k update operations. Each operation is represented as a triplet: [startIndex, endIndex, inc] which increments each element of subarray A[startIndex ... endIndex] (startIndex…

Given a singly linked list, group all odd nodes together followed by the even nodes. Please note here we are talking about the node number and not the value in the nodes. You should try to do it in place. The program should run in O(1) space complexi…

今天使用SVN提交项目时,出现了这样的提示:"XXX" is scheduled for addition, but is missing.(无关紧要的东西用XXX代替). 看报错说明是这样的:"XXX"已经被列为添加状态,但我们提交时却缺少"XXX"这个. 原因是:之前用SVN提交过的文件/文件夹,被标记为"addition"状态,等待被加入到仓库.虽然你把这个文件删除了,SVN提交的时候还是会尝试提交这个文件,所以就会提示…

1.word-wrap和word-break区分. 来源场景:机械租赁mvc驾驶员信息查看: 当备注的文字多的时候,第一列的值成这模样: 解决方案:设置table 的td可自动换行.首先table设置固定样式:table-layout:fixed 再把td样式改成: td {         word-wrap: break-word;     }.   2.奇偶行.列设置样式. 来源场景:设置好换行后,可第一列太宽,用内联样式设置td宽度也不管用,如下图所示: 解决方案:最后原因是:在tabl…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1010 题目大意: 输入 n m t,生成 n*m 矩阵,矩阵元素由 ‘.’ 'S' 'D' 'X' 四类元素组成. S'代表是开始位置: 'D'表示结束位置:'.'表示可以走的路:'X'表示是墙. 问:从‘S’  能否在第 t 步 正好走到 'D'. 解题思路: 平常心态做dfs即可,稍微加个奇偶剪枝,第一次做没经验,做过一次下次就知道怎么做了.最后有代码注释解析. AC Code: #includ…

except for 除了...以外(与 except for 连用的整体词与 except for 所跟的词往往不是同类的,是指整体中除去 一个细节.) eg:Your composition is good except for a few spelling mistakes.        除了几处拼写错误以外, 你的作文写得很好. in addition to除...之外(还)[及物] eg:In addition to French, he has to study Japanese.…
