The problem to merge two sorted arrays can be done in 3 different methods. They are
Method 1: By traversing both the arrays to keep track of the current element in each array and finding the minimum value among the two and updating the output_array with the least value.
Method 2: Concatenate the two arrays into one and then sort the entire array.
Method 3: Another approach is by using min-heaps. Take the first element from both the arrays and add it to the min-heap and output the root element from the min-heap to the merged_sorted_array and continue the same until all the array elements have been processed.
An easier approach to merge two sorted arrays would be by traversing both arrays to keep track of the current element in both arrays, finding the least value among the two and updating the final array with the least value.

In this approach, two arrays are merged into one and then the merged array is sorted finally.
