Design a program that asks the user to enter a series of 20 numbers. The program should determine whether the number is valid by comparing it to the following list of valid charge account numbers:
5658845 4520125 7895122 8777541 8451277 1302850
8080152 4562555 5552012 5050552 7825877 1250255
1005231 6545231 3852085 7576651 7881200 4581002

These numbers should be stored in an array. Use the sequential search algortithm to locate the number entered by the user. If the number is in the array, the program should display a message indicating the number is valid. If the number is not in the array, the program should display a message indicating the number is invalid. 
This assignment gives you a chance to use an array to check the input validity of an account number.
