LANGUAGE: JAVA

CHALLENGE:

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
o 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
o initialize the portion of the array consisting of the first n-1 elements (i.e., the other elements of the array )
Write a void method 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.

SOLUTION:

void init(int array[],int length) 
{ 
    if(length==0) 
    { 
        return; 
    } 
    else 
    { 
        init(array,--length); 
        array[length]=length; 
    } 
}
