Alien username

Input Format The first line contains a single integer, , denoting the number of usernames. Each line of the subsequent lines contains a string denoting an alien username to validate. Constraints Output Format Iterate through each of the strings in order and determine whether or not each string is a valid alien username. If a username is a valid alien username, print VALID on a new line; otherwise, print INVALID. Sample Input 3 _0898989811abced_ _abce _09090909abcD0 Sample Output VALID INVALID INVALID Explanation We validate the following three usernames: _0898989811abced_ is valid as it satisfies the requirements specified above. Thus, we print VALID. _abce is invalid as the beginning _ is not followed by one or more digits. Thus, we print INVALID. _09090909abcD0 is invalid as the sequence of English alphabetic letters is immediately followed by a number. Thus, we print INVALID.
