Implementing a Least Recently Used (LRU) Cache in Go
Aditya Bhuyan This program demonstrates the design and implementation of an LRU cache using Go. The LRU cache discards the least recently used items first and is commonly used to protect against…

Evaluate Postfix Expression Using Stack in Go
This program demonstrates how to evaluate a postfix expression using a stack in Go. Postfix expressions are advantageous in computational contexts because they remove the need for parentheses to dictate…
Sort Stack Using Another Stack in Go
This program sorts a stack of integers in ascending order using an additional stack. The main idea behind this method is to use the second stack as a temporary storage…
Sliding Window Maximum in Go
This program demonstrates how to find the maximum value in each sliding window of size k in an array using the Go programming language. The key technique employed is the…
Find Maximum in Each Sliding Window of Size K
This program finds the maximum value in each sliding window of size \( k \) within a given list. It utilizes an efficient algorithm using a deque (double-ended queue) to…
Sort Stack Using Another Stack in Python
This program sorts the elements in one stack using another temporary stack. The algorithm ensures that the temporary stack always holds the elements in sorted order, thus effectively sorting the…
Evaluate Postfix Expression Using Stack in Python
This program evaluates postfix expressions using a stack. Postfix notation, also known as Reverse Polish notation, is a mathematical notation in which each operator follows all of its operands. It…
LRU Cache Implementation in Python
This program implements a Least Recently Used (LRU) cache using Python. The LRU cache is designed to hold a specific number of items and evicts the least recently used item…
Circular Queue Implementation in Python
This program implements a circular queue using a fixed-size list. The circular queue overcomes the limitation of wasting spaces in normal queue operations by reconnecting the end of the queue…
Min Stack Implementation in Python
This program demonstrates a stack that supports not only push and pop operations but also retrieving the minimum element in constant time. The structure of this specialized stack includes an…
