Given an integer representing a 10-digit phone number, output the area code, prefix, and line number, separated by hyphens. ex: if the input is: 8005551212 the output is: 800-555-1212 hint: use % to get the desired rightmost digits. ex: the rightmost 2 digits of 572 is gotten by 572 % 100, which is 72. hint: use // to shift right by the desired amount. ex: shifting 572 right by 2 digits is done by 572 // 100, which yields 5. (recall integer division discards the fraction). for simplicity, assume any part starts with a non-zero digit. so 999-011- is not allowed.
