In Linux

Part-1:

1. Write a program to continuously read numbers. Save all the odd numbers in one file and all the even numbers in another file. When you enter -1, you should stop reading more numbers.
2. Write two scripts called encryption and decryption. Test both scripts by encrypting a file called file1 and save the result in file2. Then use file2 as the input to the decryption script and check if the output is the same as file1.
