oh yes
i dont main for loop
I do not remember the text of a good question

****************************************
public int Evaluate(s,t){
for {
if(s==0 || t==0)
return 0;
}
else if{
y=Evaluate(s,t-1);
return s+y;
}
}

****************************************

By using stack to find
z=Evaluate(2,2)=???????????????????
Dont use Recourion



The solution described in the link http://www.4shared.com/photo/0Nu72OYi/9999999999.html

Is the correct solution, as told by Dr.
