Obligation:
need to prove termination of the following program:
package Nest;

public class Nest{
    public static int nest(int x){
		if (x == 0) return 0;
		else return nest(nest(x-1));
    }

    
    public static void main(final String[] args) {
        final int x = args[0].length();
        final int y = nest(x);
    }
}
