When mehtod x calls method y , method y called methhod z, and method z calles method x, this is called
a. an error
b. mutual recursion
c. tail recursion
d. indirect recursion

D.Indirect Recursion.

Explanation:

Indirect recursion is when a method calls other method which calls the original method again.

For example:-

public static int mthd1( int n)

{

if (n == 0)

return 0;

else

return (mthd2(n-1));

}

public static int mthd2(int n2)

{ return mthd1( n2-1); }

This is an example of indirect recursion.Where mthd1 calls mthd 2 and mthd 2 calls mthd 1 again.
