ARRAYS
This is the one of most important data structure that is generally easy to understand but algorithms and concepts of this topic can be very tricky and it is asked in almost every tech company. Algorithms such as Binary Search, Sorting, Maximum Subarrays, and Searching are must to do in order to get a good grasp of this topic.

Advantages and Disadvantages of Array
Arrays offer several advantages and disadvantages compared to other data structures. Below are the advantages and disadvantages.
Advantages of Arrays:
1. Random Access: Arrays provide constant-time access to elements based on their index. This ...
Array Sorting
Array Sorting
The bubble sort algorithm is a simple comparison-based sorting algorithm. It repeatedly steps through the list, compares adjacent elements, and swaps them if they are in...
Extra Sorting
Extra Sorting
This sorts an array in an ascending order through iterating from first to second last element. By sorting the array in ascending order first ...
Linear Search
Linear Search
In this searching algorithm, each element is sequentially searched until a match is found or the entire array has been traversed. It is applicable to both sorted and unsorted arrays.
Algorithm
1. Compare target element with each element of arra...

A Brief Introduction to Binary Search
Binary search is used for searching in sorted arrays or lists only. It follows a divide-and-conquer approach by repeatedly di...
Quick Search
Quick Search
Quick search, also known as QuickSelect, is a selection algorithm used to find the k-th smallest element in an unsorted array.
Worst Case Time Complexity:
- In the worst case, QuickSelect has a time complexity of O(n^2), where n is the num...
