24-hour time (also known in the U.S. as military time) is widelyused around the world. Time is expressed as hours since midnight.The day starts at 0000, and ends at 2359. Write a program thatconverts am/pm time to 24-hour time. If the input is 2:30 pm, theoutput should be 1430. If the input is 12:01 am, the output shouldbe 0001.

Hints:

• Think of how each hour should be handled. 12:00 am -12:59 ambecomes what? 8:00 am becomes what? 12:00 pm? 1:00 pm? Group thehours into cases that should be handled similarly (e.g., 1:00 am to11:00 am are handled the same).

• Declare variables for hoursAmPm, minAmPm, and hours24. Note thatminutes for 24-hour time remain the same as for am/pm, so no extravariable is needed.

• Use an if-else statement to detect each case, and set thehours24 appropriately.

• When outputting hour24, check if the hour is 0-9 (just check for< 10). If so, output a "0". So 7 will be output as 07. Do thesame when outputting the minutes
