    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?

    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 ?

    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?
