The elements of an integer -valued array can be initialized so that a[i] == i in

Question

The elements of an integer -valued  array can be initialized so that a[i] == i in a recursive fashion as follows:

An array of size 0 is already  initialized ;

Otherwise

set the last element of the array to n-1 (where n is the number of elements in the array , for example, an array of size 3 will have its last element -- index 2-- set to 2; and

initialize the portion of the array consisting of the first n-1 elements (i.e., the other elements of the array )

Write a void function named  init that accepts an integer  array , and the number of elements in the array and recursively initializes the array so that a[i] == i.

Explanation / Answer

void f( int arry[], int size)
{
if(size == 0) { arry[0] = 0; return;}

arry[size] = size;
f(arry,size -1);
}

i think this logic will be sufficient for the qote.
