What Is the Time???

Limits: 1s, 512 MB

Rihan has an analog clock with no numbers 1,2, …, 12, or any indicator that can tell what the time is. So he had a plan. Another device he had, which had numbers 1,2, …, 12, was arranged in a clockwise circle, and Rihan placed his watch at the middle. He thought now he could tell the time exactly. But the problem is, the machine rotates counter-clockwise. Rihan therefore found an equation indicating the relationship between clock speed and machine’s velocity. The equation is: 2M-3C =0 (here M = velocity of machine and C = velocity of clockwise).

Now, Rihanna wants to create a computer program so that if the time input is given according to the number of indicators of the machine, it will output the correct time. As you’re a programmer, can you help Rihan creating a program for him?

Input

T (Number of testcase)

HH:MM:SS (HH=hours, MM=minutes, SS=seconds)-> For each testcase.

Constraints:

1<=T<=100

1<=HH<=12

0<=MM<=59

0<=SS<=59

Output

Simply print the correct time in the format of HH:MM:SS

It is necessary to print 01 instead of 1. Output should be printed for every testcase separating by a newline.

For more clearification see sample testcase.
