Algorithm or program to check for balanced parentheses in an expression using stack data structure. For example: [(+) * (-)] // true {[()]} // true {(}) // false {*) //false The idea to solve the problem is: opening and closing parentheses should hav…

第一道被我AC的hard题!菜鸡难免激动一下,不要鄙视.. Given a string containing just the characters '(' and ')', find the length of the longest valid (well-formed) parentheses substring. For "(()", the longest valid parentheses substring is "()", which has le…

Given a string containing just the characters '(' and ')', find the length of the longest valid (well-formed) parentheses substring. For "(()", the longest valid parentheses substring is "()", which has length = 2. Another example is &…

Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. The brackets must close in the correct order, "()" and "()[]{}" are all valid but "(]" and "([)]"…

括号匹配问题,使用栈的特点,匹配则出栈,否则入栈,最后栈为空则全部匹配.代码如下: class Solution { public: bool isValid(string s) { stack<char> T; ;i < s.length();i ++) { ) { T.push(s[i]); } else T.pop(); } if(T.empty()) return true; else return false; } };…

这个错误错了几次,必须做个标记 解决方法非常的简单: 最新的19版本会在你的项目下建立一个依赖包 Android Dependencies,在eclipse中右键这个文件夹,在Build Path选项中选择 remove it from build path...然后就没问题了.…

在android高版本开发环境(sdk 4.4)导入低版本(sdk 3.0)的工程时编译报错,报错信息如:Conversion to Dalvik format failed: Unable to execute dex: java.nio.BufferOv,这个错误是由于错误的添加了不必要的core library或重复添加了同一个library jar包措施产生冲突造成的,可以采用一下方法解决: 1)修改SDK 选择工程,build path –> configure build path…

今天在编译别人的project时遇到了这个错误,心想应该不是代码的问题.网上搜了一下,应该是sdk版本设置的问题,要设置为最新sdk版本才可以. 解决办法就是修改project.properties里的target=android-19 http://stackoverflow.com/questions/20778767/unable-to-execute-dex-java-nio-bufferoverflowexception-check-the-eclipse-log-f…

Linear data structures linear structures can be thought of as having two ends, whose items are ordered on how they are added or removed. What distinguishes one linear structure from another is the way in which items are added and removed, in particul…

You are given a string consisting of parentheses () and []. A string of this type is said to be correct: (a) if it is the empty string (b) if A and B are correct, AB is correct, (c) if A is correct, (A) and [A] is correct. Write a program that takes…

SPOJ - BALNUM 题意: Balanced Numbers:数位上的偶数出现奇数次,数位上的奇数出现偶数次(比如2334, 2出现1次,4出现1次,3出现两次,所以2334是 Balanced Numbers) ,求一个区间内有多少Balanced Numbers. 解题思路:看题很容易想到数位dp,但是怎么记录某数字出现的次数呢?由于某数字出现的次数只与奇偶有关,与大小没有关系,所以我们可以分别用0,1,2来表示某数字没有出现,出现奇数次,出现偶数次,然后就可以用三进制来记录所有数字…
