N(n-1)/2 formula
N(n-1)/2 formula- As @betlista has said, n (n1)/2 is the sum of the first (n1) numbers, that is 1 2 3 4 (n1) Now one might think that there is not much use for this formula, but when you do some research, you can find interesting uses for it @betlista has explained a few uses Here is a link which explains one usage I have to calculate n(n1)/2 for every (ai1ai1) where i is the index of the array and a is the generalized array Also consider corner cases from both ends They are to subtract 1 from first digit and then calculate n(n1)/2 and to subtract last digit from 11 and then calculate n(n1)/2 For eg

To sum integers from 1 to N, start by defining the largest integer to be summed as N Don't forget that integers are always whole and positive numbers, so N can't be a decimal, fraction, or negative number Once you've defined the integer value of N, use the formula sum = (N × (N1)) ÷ 2 to find the sum of all the integers between 1 and N!
