What Does the Limit of Summation i<j Mean?

[AKBAR]

Hi,

I'm having some trouble understanding what is meant when the limit of a summation is i<j. Does it mean the limits are i = 0 to i = j?

Thanks!

If i is always strictly less than j, then index i's maximal value is j-1.

Hello,

The limits of summation i<j means that the summation is only being performed for values of i that are less than j. For example, if the summation is written as Σi<j, then the summation would only be performed for i = 0, 1, 2, ..., j-1. This is also known as a "restricted summation" where the range of values for i is limited to be less than j.

I hope this helps clarify the concept for you. If you need further assistance, please don't hesitate to ask.
