Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. In this post , we will see how to implement Queue using Array in java. Queue is abstract data type which demonstrates First in first out (FIFO) behavior. We will ...
Implementation of a One-LLID-per-Queue DBA Algorithm in EPONHowever
Pop operation algorithm The basic idea is to transfer n-1 elements (let n be the total no of elements) to other queue and delete the last one from a queue to perform the pop operation. If q1 is not empty then transfer n-1 elements from q1 to q2 and DeQueue the last element and re...

Recently, I was solving the Graphs section of the CSES problemset and encountered this problem. I used dijkstra algorithm to solve it. I generally use the template from here, but in this question, this implementation gave me WA. When I used another implementation using visited array, it gave...

A reference implementation of the above algorithm, implemented with safe memory reclamation using hazard pointers. ck_hp_stack A reference implementation of a Treiber stack with support for hazard pointers. ck_stack A reference implementation of an efficient lock-free stack, with specialized variants ...
For the array-based implementation of a stack, the push and pop operations take constant time, i.e.O(1). Applications of Stack Data Structure Although stack is a simple data structure to implement, it is very powerful. The most common uses of a stack are: ...
