Given two sorted arrays arr1[] and arr2[] of sizes n and m in non-decreasing order. Merge them in sorted order without using any extra space. Modify arr1 so that it contains the first N elements and modify arr2 so that it contains the last M elements.

Merge-Without-Extra-Space

Given two sorted arrays arr1[] and arr2[] of sizes n and m in non-decreasing order. Merge them in sorted order without using any extra space. Modify arr1 so that it contains the first N elements and modify arr2 so that it contains the last M elements.

Input: n = 4, arr1[] = [1 3 5 7] m = 5, arr2[] = [0 2 6 8 9] Output: arr1[] = [0 1 2 3] arr2[] = [5 6 7 8 9] Explanation: After merging the two non-decreasing arrays, we get, 0 1 2 3 5 6 7 8 9.
