why 'tabulate' function does not work here. It gives an error saying undefined function.

Ashan, tabulate is in stats. Cody does not have Statistics Toolbox.
the in-build function tabulate cannot used in here.
I never thought I could use this line of code for this problem but what do you know
i have used a loop construct for this but apparently there are far faster ways (length: 20ish instead of 80-100)
