Here, we are using the formula sum= (n+1)* (n+2)/2 instead of sum= (n)* (n+1)/2 because the total number of elements here is n but as one element is missing so the total number adds up to n+1. Share. One important thing to be kept in mind is that the data values are to be entered in a sorted order. If an element it found to be greater than this, then the index is updated to the index of this newly found largest element. I think I've overthought it a bit - my method just gets longer and longer. Fixed it: float point comparisons use a tolerance, or epsilon. This actually returns the mode, but it can't deal with two modes. This is necessary because we need to find the middle element.
