Binary Search Problem
Binary Search is a classic searching algorithm that efficiently finds the target element in a sorted array. Given a sorted array of integers nums and a target element target, you…
Single Element in a Sorted Array
Given a sorted array of integers where every element appears twice except for one, you need to find that single element that appears only once.
Find First and Last Position of Element in Sorted Array
Given a sorted array of integers nums and a target element target, you need to find the starting and ending position of target in the array. If the target element…
Search in Rotated Sorted Array
We can solve this problem using a modified binary search algorithm. We can identify whether the target element lies in the left or right half of the rotated array based…
Find In Mountain Array
A mountain array is defined as an array that increases to a peak element and then decreases. You need to find the target element target in the mountain array and…
