题目大意: 给你一个n 代表有n列 火车,  第一个给你的一个字符串 代表即将进入到轨道上火车的编号顺序, 第二个字符串代表的是 火车出来之后到顺序, 分析一下就知道这,这个问题就是栈, 先进后出吗, 就是问你这个编号有没有可能出现, 有可能的话输出顺序,没可能直接输出No 题目分析: 我们用栈进行模拟, 先判断是否有这种出栈的可能, 假如有这种可能的话我们在模拟 一遍出栈的顺就行了. 每一次有新元素入栈我们就判断他是否雨 第二个字符串的第一个元素是否相等, 假如一样, 就让次元素出栈. 代码…

卡特兰数: Catalan数 原理: 令h(1)＝1,h(0)=1,catalan数满足递归式: h(n)= h(1)*h(n-1) + h(2)*h(n-2) + ... + h(n-1)h(1) (其中n>=2) 另类递归式: h(n)=((4*n-2)/(n+1))*h(n-1); 该递推关系的解为: h(n+1)=C(2n,n)/(n+1) (n=1,2,3,...) 最典型的四类应用:(实质上却都一样,无非是递归等式的应用,就看你能不能分解问题写出递归式了) 1.括号化问题. 矩阵链乘…
