Sort Messages – Chronological Order

The program must accept N messages shared between the two persons A and B in a single day (from 00:00:00 to 23:59:59) as the input. Each message contains the author’s name, the time of the message sent (in 24-hour format HH:MM:SS) and the content of the message. The program must sort and print those N messages in the chronological order as the output.
Note: More than one messages at a time are not possible.

Boundary Condition(s):
2 <= N <= 50
12 <= Length of each message <= 100

Input Format:
The first line contains N.
The next N lines, each containing the author’s name, the time of the message sent and the content of the message separated by a space.

Output Format:
The first N lines, each containing the author’s name and the content of the message separated by a colon.

Example Input/Output 1:
Input:
4
A 07:32:21 u can upload first
A 07:32:30 then you can tag
A 07:33:10 please ping me once it is done.
B 07:32:41 okay

Output:
A:u can upload first
A:then you can tag
B:okay
A:please ping me once it is done.

Explanation:
The first message u can upload first was sent at 07:32:21.
The second message then you can tag was sent at 07:32:30.
The third message please ping me once it is done was sent at 07:33:10.
The fourth message okay was sent at 07:32:41.
After sorting the 4 messages in chronological order, the order of the messages become 1, 2, 4 and 3.
Hence the output is
A:u can upload first
A:then you can tag
B:okay
A:please ping me once it is done.
