What would be the subsets for {1, 1, 3}?

function SubSet (array, startIndex, endIndex){ var subset =[]; for (;startIndex < endIndex; startIndex++){ subset.push (array [startIndex]); } return subset; } won't work for non adjacent sets such as 1, 3 but you can modify code to warp around index if you like.

i think (idk what language) it works like this a=[1,2,3]; action with a(0) (to get 1) action with a(0, 1) (to get 1,2) im not sure i used the correct brackets
