I am wondering if there is any way I can find a formula that will solve
the following condidion
CONSTANTS: MAX=1000
MIN=0
PRECONDITIONS
Z=SOME NUMBER (arbitrary)
N=0;
IF N=0 THEN maxx=MAX;
maxy=MAX;
minx=MIN;
miny=MIN;
POST CONDITION: SPACE is returned as the answer
FORMULA:
FOR N=0 TO N=Z DO N+1 /* RUN THE LOOP Z TIMES */
{
SPACE=(maxx-minx)/(2*MAXAXIS);
maxy=maxx-1;
maxy=maxy-1;
minx=minx+1;
miny=miny+1;
}
--------------------------
I hope you understand what I want, I originally wrote this in C, but tried
to write it more universally for this post.
what I want (if possible) is some formula that wont have to go through
this for loop/series sum ,to get the desired number.Since the Z value can
easily be over 10000 the time it take is unacceptable (Im using it for
graphics).
I need some function that takes in a z value, and pops out SPACE as the
answer, If any of you know how to do this, or perhaps doing it some other
way, please e-mail me asap....one more thing, can you explain how you got
the answer, I deal with these sorts of problems all the time, but have no
mathematical insight to them.....If you don have time to explain it, could
you tell me what I can study to learn about it. THANKS ALOT FOR YOUR HELP!
