Problem Statement: Given an array of integers, rotate it by 'k' steps to the right. Example: For [1,2,3,4,5] with k=2, the result would be [4,5,1,2,3].

Explanation

An anagram is a word or phrase that is created by rearranging the letters of another word or phrase, using all the original letters exactly once. The goal of this problem is to determine if two given strings are anagrams of each other. For instance, the words "listen" and "silent" are anagrams.

Explanation

The goal is to implement a queue using two stacks. A queue follows the First-In-First-Out (FIFO) principle, whereas a stack follows the Last-In-First-Out (LIFO) principle. By cleverly using two stacks, we can emulate the behavior of a queue.

Explanation

A linked list is a linear data structure where each element is a separate object. Each element (which we will call a "node") of a list consists of two items:

1. The data (in case, an integer value).
2. A reference (or "link") to the next node in the sequence.

Explanation

A Binary Search Tree is a binary tree data structure where each node has at most two children, referred to as the left child and the right child. For each node, all elements in the left subtree are less than the node, and all elements in the right subtree are greater than the node.

  1   4 6   8

In the above diagram:

• Node 5 is the root.
• 3 and 7 are children of 5.
• 1 and 4 are children of 3.
• 6 and 8 are children of 7.
