Please I want a solution to this question؟

[salemqeshta]

public int Evaluate(s,t){
for loop {
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
please help me ?!!

Note :
When I answered the question
The answer is 6
But some of my answer was 4
I am confused about now

[salemqeshta]

I'm not quite sure what you're asking.

Is Evaluate given in some real language or is it pseudocode? What does,

for loop {

mean?

[salemqeshta]

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

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

Is the correct solution, as told by Dr.



Thus, the question was almost



Thank you for your interest

How do you solve it using recurion ?

[Lazyboy]

Hello, strange, so strange, I am still think it is 0 not 4

1.public int Evaluate(s,t){
2.{
3.if(s==0 || t==0)
4.return 0;
5.}
6.else if{
7.y=Evaluate(s,t-1); // this
8.return s+y;
9.}
10.}

Line 7 rerun line 1, so no value is put for y
t=2-1=1
s=2
line 3 checks t and s
unsatisfactorily, line 6 come again, line 7 again rerun line 1, still no value for y
t=1-1=0
s=2
Now t=0
line 2-3 checks t=0 so satisfied it returns 0

So the final result is 0, line 8 never reaches

Answer=0

Am I right ?

Am I right ?

Does it stay put now, the 1 to 10 lines? Is this the version of the Evaluate function you're asking about?

And what are you asking again please? Be precise.

And who is salemqeshta in relation to lazyboy?

Sorry for letting out some steam here but why is it so god dammed hard to state a problem in a precise and understandable way?
