Show what would be displayed by the following calls to the recursive method (DO NOT run the program)

a)

int recur(int n)

{

if (n < 0)

return 1;

else if (n < 10)

return 1;

else

return (1 + recur (n / 10));

}

What would be displayed by the following calls?:

System.out.println(recur(5));

System.out.println(recur(25));

System.out.println(recur(250));

b)

int recur2(int n)

{

if (n < 0)

return 1;

else if (n < 10)

return n;

else

return ((n % 10) + recur2(2 / 10 ));

}

What would be displayed by the following calls?:

System.out.println(recur2(5));

System.out.println(recur2(25));

System.out.println(recur2(250));
