题目:52张扑克,从左到右在平面上排列,按着如下规则处理: 1.按照从左到右的顺序,如果一张牌和左边的第一张或者第三张匹配,就把它放到对应的牌上面. 2.如果可以移动到多个位置,移动到最左端的牌上面.(匹配:花色或者数值相同) 分析:数据结构.栈.模拟.对于每叠牌建立一个栈,进行模拟即可. 注意:每次只移动每叠牌的最顶上的牌. #include <iostream> #include <cstdlib> #include <cstdio> using namespace…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5512 学习菊苣的博客,只粘链接,不粘题目描述了. 题目大意就是给了初始的集合{a, b},然后取集合里的两个元素进行加或者减的操作,生成新的元素.问最后最多能生成多少个元素.问答案的奇偶性. 首先一开始有a, b.那么如果生成了b-a(b>a),自然原来的数同样可以由b-a, a生成(b != 2a). 于是如此反复下去,最后的数必然是可以由两个数p, 2p生成的. 于是所有的数肯定可以表示成xp+…
