Your task is to write a program that
(1) prompts the user for the number of work weeks available (an integer);
(2) prompts the user for the names of the input and output files (strings);
(3) reads the available projects from the input file;
(4) solves the corresponding knapsack problem, without repetition of items; and
(5) writes to the output file a summary of the results, including the expected profit and a list of the best projects for the company to undertake.

Here is a sample session with the program:
Enter the number of available employee work weeks: 10
Enter the name of input file: KnapsackData1.txt
Enter the name of output file: Output1.txt
