Consider you are asked to decode a secret message. The coded message is in numbers and each number stands

for a specific letter. You discover enough of the secret code to decode the current message. So far, you know:

1 represents D

2 represents W

3 represents E

4 represents L

5 represents H

6 represents O

7 represents R

Write a program that prompts the user for 10 numbers, one at a time, and prints out the decoded message. If the user enters a number that is not one of those already deciphered, prompt him/her for a new number. Test your code with the following input: 5 3 4 4 6 2 6 7 4 1
