Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
/*how to use two stacks to implement the queue: offer, poll, peek,size, isEmpty offer(3) offer(2) poll() offer(1) peek() offer(6) poll() poll() 3 2 2 1 in (3 2) (1 6) out (2) (3) 6 (1) stack1(in): is the only stack to store new elements when adding a new ...
CC150 : Queue by Two Stacks 两个stack来实现queue,相似的是两个queue也能实现stack。 classSolution {publicStack<Integer> sortStack(Stack<Integer>s1) { Stack<Integer> s2 =newStack<Integer>();while(!s1.isEmpty()) {inttemp =s1.pop();while(!s2.isEmpty() && s2.peek() >temp) { s1.push...
q.add("c"); q.remove(); // should be "b", but is "c". q.remove(); // should be "c", but is "b". Using two stacks to implement a queue is not a logical data structure as far as I am concerned. There are many better ways. Share Follow answered Jun 19, 2014 at ...
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....
The Contains method is used to show that the string "four" is in the first copy of the queue, after which the Clear method clears the copy and the Count property shows that the queue is empty. C# Copy Run using System; using System.Collections.Generic; class Example { public static vo...
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 a stack implementation and it gives...
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. ...
