DearAll, Please, help! I have two list list1={a,b,c,d,e} list2={3,2,5,1,6} and I want to apply a modified version of FoldList to list1 in the following way: list2 indicates that element a appears only 3 times (if space enough) beginning from the beginning of the list , element b appears 2 times, c - 5 times , etc. So the output should be GeneralizedFoldList[list1,list2]={a,a+b,a+b+c,c+d,c+e} Thanks for any hints, arek
