what is the fastest way to sum up all the N/2 elements in an N by N array? Any language will do....
uhh.. if I read it correctly, sum up all even numbers in an nxn array?
or do you mean elements with an even numbered subscript
maybe you meant N^2?
how to add up all the n/2 elements in the n by n array? =)
can only think up of a looping function, which will be a problem if n is very large
sorry but that does not compute. What is a n/2 element?

asks
if it's the first n/2 half or the last n/2 half?

all the n/2 elements in the array... :S
still wonders if you mean 2|n elements
maybe each element divided by 2??
"an n/2 element" doesn't compute 
sorry
