This post will discuss how to implement twostacksin a single array efficiently. A simple solution would be to divide the array into two halves and allocate each half to implement two stacks. In other words, for an arrayAof sizen, the solution would allocateA[0, n/2]memory for the first...
We are going to create a data structure called twoStacks which will be using only a single array to store the data but will act as two different stacks. The twoStacks data structure will perform following operations. push1(elm): This will add data in the first stack. push2(elm): This...

Implement Queue by Two Stacks As the title described, you should only use two stacks to implement a queue’s actions. The queue should support push(element), pop() and top() where pop is pop the first(a.k.a front) element in the queue....
正如标题所述,你需要使用两个栈来实现队列的一些操作。 队列应支持push(element),pop() 和 top(),其中pop是弹出队列中的第一个(最前面的)元素。 pop和top方法都应该返回第一个元素的值。 样例 比如 push(1), pop(), push(2), push(3), top(), pop(),你应该返回1,2和2 ...

As the title described, you should only use two stacks to implement a queue's actions.The queue should support push(element), pop() and top() where pop is pop the first(a.k.a front) element in the queue.Both pop and top methods should return the value of first element. ...
Implement a queue ↴ with 2 stacks. ↴ Your queue should have an enqueue and a dequeue method and it should be "first in first out" (FIFO). Optimize for the time cost of mm calls on your queue. These can be any mix of enqueue and dequeue calls. Assume you already have ...
