Have the function CountingMinutes(str) take the str parameter being passed which will be two times (each properly formatted with a colon and am or pm) separated by a hyphen and return the total number of minutes between the two times. The time will be in a 12 hour clock format.
For example: if str is 9:00am-10:00am then the output should be 60. If str is 1:00pm-11:00am the output should be 1320.

+ min + (MINUTES_IN_DAY / 2) :
(hour * MINUTES_IN_HOUR) + min;
return minOfDay > MINUTES_IN_DAY ?
minOfDay - MINUTES_IN_DAY : minOfDay;
}

if (startTime <= endTime) return

return (MINUTES_IN_DAY - startTime) + endTime;
}

Counting Minutes Coderbyte Solution In Python
def turn24H(time):

== "am" else [int(result[0])+12, int(result[1])]
result[0] = result[0] if (result[0]!=12 and result[0]!
=24) else result[0]-12
return result
def CountingMinutesI(str):
time1,time2 = [turn24H(time) for time in str.split("-")]
if (time1[0] <= time2[0]):
return 60* (time2[0] - time1[0]) + time2[1] - time1[1]
else:
return 60 * (24 - time1[0] + time2[0]) - time1[1]
+ time2[1]
