Read the paper located at this url:      https://www.nku.edu/~christensen/simplified%20IDEA%20algorithm.pdf (Links to an external site.)
Listen to the recorded lectures on encryption. 
Implement the “The Simplified Encryption Algorithm” located in the paper in this manner.
Accept as input a a single string of text from standard input.
The string will contain only ascii characters.
There must be at least 16 characters in the strubg.
The limit on the string will be 256 characters. 
Accept from standard input a 32-bit key in binary.  Be sure to remember that the key as read in will be as characters and you must convert it to an unsigned integer. 
Encrypt the string using the 32-bit key and output an encrypted text to standard output
