PROGRAMMING:[branch] [time conversion a --]

Now input a 24-hour time, please program to convert it to 12 hour time format, and output the converted time. If the original time is in the morning, then the space and am need to be output after the conversion time. If the original time is in the afternoon, the space and PM need to be output after the conversion time. Refer to the example for details.
Note: in the 24-hour system, \ [00:00 ~ 12:00 \] is considered as morning, \ [12:01 ~ 23:59 \] is considered as afternoon.
Prompt: for the format of output time: minutes, please use printf (% 02D% 02D am or PM "),% 02D means the width of 2 digits, and 0 is filled in the front if the number is less than 2 digits.
Scanf ("% d") can still be used to output data with 0 in the front. For example, scanf ("% d% d", & H, & M) can be used to input 09:09.
