Welcome to the daily solving of our PROBLEM OF THE DAY with Yash Dwivedi . We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Arrays but also build up problem-solving skills.

In this problem, we are given, two sorted arrays of size n and m respectively, find their union. The Union of two arrays can be defined as the common and distinct elements in the two arrays. Return the elements in sorted order.

Example :

Input: 
n = 5, arr1[] = {1, 2, 3, 4, 5}  
m = 5, arr2 [] = {1, 2, 3, 6, 7}
Output: 
1 2 3 4 5 6 7
Explanation: 
Distinct elements including both the arrays are: 1 2 3 4 5 6 7.

Give the problem a try before going through the video. All the best!!!
