letter frequency

file handling

open CSV file,
read and store text and number values into parallel arrays,
close file

standard algorithms

use count, find max
write selected data to a new file
this task assumes the developer is already familiar with the constructs described below, minimal support
developers should re-use previous code to complete this project
