Looking for SML(Standard ML) developer

I'd like to ask you to write 6 codes with SML(Standard ML). The code is a beginner to intermediate level. It wouldn't be too long if you know SML. The first task in this project is; Write a recursive function (range) that takes 3 numbers as arguments (begin, end, inc) and return a list that starts at begin and each subsequent number increases by inc and the list has a last value which is less than or equal to end. Assume that end > begin and inc is always +ve. (range 2 15 3) should return '(2, 5, 8, 11, 14)
