4 * You are given a 0-indexed array of strings details. Each element of details provides information about a given passenger compressed into a string of length 15. The system is such that:
5 * 
6 * 	The first ten characters consist of the phone number of passengers.
7 * 	The next character denotes the gender of the person.
8 * 	The following two characters are used to indicate the age of the person.
