题目链接:Shuffle'm Up 除了英文题有点恶心.发现模拟 + bfs 就可以过的时候,就是水了. 一个bug 就是filp函数得到string s12失败了.恩.据大腿告知,string 并不指定字符串的初始化长度是0,也就是说我每个元素的赋值是没有意义的.或者.string 是引用型数据类型,所以名字是一个指针吧.然后str.resize()函数愉快的解决了这个问题. 还有就是对题意.字符串从左到右是从下到上.我是懵了一下的. 题意思路见代码吧. /* 题目很长.也没有看.百度到题意.…

题目: 现有字符串s1.s2.s12,其中s1.s2的长度为len,s12的长度为2*len. 是否可以通过一些操作使s1和s2转换合并成s12? 变换的操作规则如下: 假设s1=11111,s2=00000 变换后的序列 s=0101010101 假设s1=12345,s2=67890 变换后的序列 s=6172839405 如果s和s12完全相同,那么输出变换次数 如果不完全相等,s的前半部分作为s1,后半部分作为s2,重复上述过程 输入: 第一行T(1≤T≤1000),代表有T组数据. 每…
