Hi @hhiteshbansal_40d12e2460a1738e
you can visualize the problem in reverse order like how the array will look when it would be sorted, now think how which element it get swapped with
eg say array is 1 3 2
then sorted array is : 1 2 3 we can see 3,2 got swapped so ans is 1
eg say array is 1 4 2 3
sorted array : 1 2 3 4, swapping 2,3 --> 1 3 2 4, again swapping 3,4 we get the original array1 4 2 3 so ans is 2
