[传送门]http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemCode=4016 [题目大意]初始有n个空栈,现在有如下三种操作: (1) 1 s v 即 s.push(v) (2) 2 s 即 s.pop() 输出弹出的元素,如果栈s为空则输出 "EMPTY" (3) 3 s t 把t栈元素全部移到s栈中,使s的尾部与t的首部相连. 现在有若干上述三种类型的操作,遇到操作2则输出相应内容. [题解]由于站的数量n和操作次数…

个人心得:算法书中的第一个例题就来了一个下马威,虽然题意很好理解但是做起来确实这么不顺手,所以自己对于搜索和堆栈理解的并不是很好, 以前也是很多这样的题目无法实施,这题要做的很明确就是输出正确的能依靠栈完成字符串的变化,很明显答案很多所以必须搜索确定出栈的位置, 但是自己无法控制好搜索,题解很清晰, 个人收获:vector 可以用于搜索更方便,然后搜索的时候注意细节和base基准情况 题目: How can anagrams result from sequences of stack oper…
