Sort int subvectors from low to high

bchinfosieeuw (72)
subsetSortedStringnumbers2 is a 2D vector containing rows of ints. I want to sort the ints in each subvector of subsetSortedStringnumbers2 from low to high. The loop around the //Printline is only sorting the first row of ints from low to high, while the ints of the next row(s) are not loading from the vector subsetSortedStringnumbers. How can I load and sort the ints of all subvectors of subsetSortedStringnumbers2?

Current output:
2;3;4;5;17922;0;

PS. insertSortStringnumbers(const vector<T>&) and insertSortNotes(const vector<T>&) are identical. You need only one of them.
