Implementation of a stack using two queuesLikewise, a queue can be implemented with two stacks, a stack can also be implemented using two queues. The basic idea is to perform stack ADT operations using the two queues.So, we need to implement push(),pop() using DeQueue(), EnQueue() ...
A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue, dequeue) with stack operations (push, pop). Implementation: Let s1 and s2 be the two stacks used for implanting the queue...
After the deletion value, we will increment the value of the front position by 1. So now, the new value of the front and rear will be 2 and 3 respectively. Program for the Implementation of Queue using Array: We have already seen how an array can be used to implement a queue. Now,...
// Push element x to the back of queue. Stack<Integer> stack =newStack<>(); Stack<Integer> aux =newStack<>(); publicvoidpush(intx) { while(!stack.isEmpty()){ aux.push(stack.pop()); } stack.push(x); while(!aux.isEmpty()){ stack.push(aux.pop()); } } // Removes the e...
Learn how to implement Stack data structure in Java using a simple Array and using Stack class in Java with complete code examples and functions like pop, push.

Working of queue: We can implement queue by using two pointers i.e. FRONT and REAR. FRONT is used to track the first element of the queue. REAR is used to track the last element of the queue. Initially, we’ll set the values of FRONT and REAR to -1. ...
Heap Sort operates in two main phases: Build Max Heap: Transform input array into max heap Extract Elements: Repeatedly remove the maximum element Visual Example of Heap Sort Process: Initial Array:[4,10,3,5,1]Step1-Build Max Heap:10/\53/\41Step2-Extract Max:1.[10,5,3,4,1]→[1,...
Using STL Vectors How To Select The Representation To Use? Conclusion Implementation Of String Arrays In C++, strings can be represented using three ways. Using Two-dimensional Character Arrays:This representation uses the two-dimensional arrays where each element is the intersection of a row and co...
