Draw a hierarchy chart that displays the modules for this problem statement Ledger's Furniture Store has 10 salespeople. Ledger's wants to produce a combined monthly sales report for all salespeople. Ledger's wants you to write a program that will allow them to enter data in any order, save the unsorted data to a file, and then produce a file in alphabetical order by name of the salespeople. The unsorted output file should be named "sales_unsorted. txt" and the sorted file should be named "sales_sorted. txt".
