Is it possible for me to use LINQ in a way that allows me to determine that "9"
is the first missing value in the sorted list without using a for-loop and comparing each value to the one adjacent to it?
var listStringVals = new [] { "7", "13", "8", "12", "10", "11", "14" };
// sort list to "7","8","10","11","12","13","14"
var sortedList = listStringVals.OrderBy(c => int.Parse(c)).ToList();
// need some magic here to get the first gap in the sorted list
