What will be the output of the following program?
public class LinkedClasses {
public static void main(String[] args) {
int count = 6;
M m = new M(); m.print(count--);
m.n = new N(); m.print(count--);
m.n.o = new O(); m.print(count--);
m.n.o.m = m; m.print(count--);
}
}
class M {
N n;
void print(int count) {
System.out.print("M" + count + " ");
if (n != null && count > 0) n.print(count - 1);
}
}
class N {
O o;
void print(int count) {
System.out.print("N" + count + " ");
if (o != null && count > 0) o.print(count - 1);
}
}
class O {
M m;
void print(int count) {
System.out.print("O" + count + " ");
if (m != null && count > 0) m.print(count - 1);
}
}
