We first make the array elements zero by choosing last index(n) and modding with 1.

Then add the prime number(P)>=n*2+1 by choosing the last index(n).Therefore all the elements of array will become prime number P.

Then Starting from initial index(1) to n-1 mod with a[i]-i which will bring us 0 ,1 ,2 ,3 ,4 to prime number(P).

We are choosing prime number >=n*2+1 because while modding with a[i]-i, a[i]-i should always be greater than all the numbers we have in the array before i index. Therefore for simplicity we've taken a number >=n*2+1.
