## What is big-Oh characterization ?

Hi All,

Can you please briefly explain the implication of the big-Oh notation in simple
English on below statement ?

Input: n and m integers
Output: The sum of product
sum <- 0
for i<-1 to n-1 do{
for j<-i to m-1 do{
sum += i * j
}
}
return sum

I could explain it to you but not as well as wikipedia. So look it up. And it has nothing to do with Java.

Regards,
Jim
