Amateur Hour

Create a function that takes time1 and time2 and return how many hours have passed between the two times.

Examples

hours_passed("3:00 AM", "9:00 AM") ➞ "6 hours"

hours_passed("2:00 PM", "4:00 PM") ➞ "2 hours"

hours_passed("1:00 AM", "3:00 PM") ➞ "14 hours"

Notes

• time1 will always be the starting time and time2 the ending time.
• Return "no time passed" if time1 is equal to time2.
