Moving zeros to the end of an array while maintaining the order of non-zero elements is a common problem in programming. In this article, we'll discuss two approaches to achieve this: one using a temporary array and another using a two-pointers techn...
Right rotating an array involves shifting the elements of the array to the right by a specified number of places. In this article, we'll discuss two efficient methods to achieve this rotation. Solution 1: Brute Force Approach (using a Temp Array) Thi...
Left rotating an array involves shifting the elements of the array to the left by a specified number of places. In this article, we'll discuss two efficient methods to achieve this rotation. Solution 1: Brute Force Approach (using a Temp Array) This ...
Removing duplicates from a sorted array is a common problem asked in many coding interviews and programming challenges. This can be approached using different methods. In this article, we'll discuss two approaches to remove duplicates from a sorted a...
There are many times we need to check if an array is sorted or not. Checking if an array is sorted can be approached in multiple ways. Here, we we'll discuss two solutions: a brute force approach and an optimal approach. Solution 1: Brute Force Appro...
Finding the second largest element in an array can be approached in multiple ways. Here, we'll discuss three methods: using sorting, a better approach with two linear traversals and an optimal single-pass approach. Solution 1: Sorting One straightfor...
