Challenge: Merge Two Sorted Arrays

Problem Statement #

In this problem, given two sorted arrays, you have to implement the int[] mergeArrays(int[] arr1, int[] arr2) method, which returns an array consisting of all elements of both arrays in a sorted way.

Method Prototype #

int[] mergeArrays(int[] arr1, int[] arr2)

Here arr1 and arr2 are sorted already.

Output #

Merged array consisting of all elements of both arrays in a sorted way.

Sample Input #

arr1 = {1, 3, 4, 5}  
arr2 = {2, 6, 7, 8}

Sample Output #

arr = {1, 2, 3, 4, 5, 6, 7, 8}
