/*
Name: main
Purpose: Get user input & action based off input
Parameters: N/A
Return Values: 1 for bad input, 0 for good input
Input: Input from keyboard, first digit is the length of the array and the following are the digits to be normalized
Output: print the input in a formatted way & print a normalized version of the array
