The stack is a linear data structure that is used to store the collection of objects. It is based on Last-In-First-Out (LIFO). Problem Statement Given a string write a program in Java to reverse a string using stacks. Below is a demonstration of the same ? Input Input string: Java ...

Write code to reverse a string such that the words are reversed as in "We apologise for the inconvenience" becomes "inconvenience the for apologise We" .Obviously (is there fun otherwise?) the problem had to be solved for a memory constraint device (constant space)....
This solution is not the best one and will be really slow if the String is very long and the stack size is of major concern. Approach 6 – Using two pointers function revStr(str) { let arr = new Array(str.length) let left = 0 let right = str.length - 1 while (left <= right...
一个栈依次压入1、2、3、4、5,那么从栈顶到栈底分别为5、4、3、2、1。将这个栈转置后,从栈顶到栈底为1、2、3、4、5,也就是实现栈中元素的逆序,但是只能用递归函数来实现,不能用其他数据结构。

I am currently using the jQuery plotting plugin (Click), but I am having trouble fetching the data out of my database. I am using PHP for the SQL part, which returns an array like this: Now I need it ... adding new row dynamic to datagrid ...
This problem can be solved by using a stack. We can loop through each element in the given array. When it is a number, push it to the stack. When it is an operator, pop two numbers from the stack, do the calculation, and push back the result. ...
题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1062 题意:转置一个字符串内的所有单词。 解法:读取‘ ’或‘\0’作为一个单词结束的标记,可用头文件<string.h>里的strrev函数转置单词,比较方便。也可以采用字符压栈的方法来转置单词(利用堆栈的先进后出性质)。或者用最传统的方法,数组存放字符,然后转...
