【算法训练营】栈合集(1) 剑指 Offer 31. 栈的压入、弹出序列 || 32. 最长有效括号 || 682. 棒球比赛 || 面试题 03.01. 三合一

输入: "((())" 输出: 4解题思路本题可以使用栈来解决。我们遍历给定的字符串，使用一个栈来保存遇到的字符的下标。当遇到左括号时，我们将其下标入栈。当遇到右括号时，我们尝试从栈中弹出一个左括号的下标，表示匹配了一个括号对。如果栈为空，则当前右括号没有匹配的左括号，我们将其下标入栈以作为新的起始点。如果栈不为空，则计算当前有效括号的长度，即当前右括号的下标减去栈顶元素的值（栈顶元素表示上一....

压入弹出堆栈算法-附LeetCode剑指 Offer 31. 栈的压入、弹出序列-题解-python && C++源代码

剑指 Offer 31. 栈的压入、弹出序列难度中等334收藏分享切换为英文接收动态反馈输入两个整数序列，第一个序列表示栈的压入顺序，请判断第二个序列是否为该栈的弹出顺序。假设压入栈的所有数字均不相等。例如，序列 {1,2,3,4,5} 是某栈的压栈序列，序列 {4,5,3,2,1} 是该压栈序列对应的一个弹出序列，但 {4,3,5,1,2} 就不可能是该压栈序列的弹出序列。示例 1：输入：pu....
