Problem Statement

Takahashi bought a table clock.
The clock shows the time as shown in Figure $1 at \mathrm{AB}$:$\mathrm{CD}$ in the 24-hour system.
For example, the clock in Figure 2 shows 7:58.

The format of the time is formally described as follows.
Suppose that the current time is m minutes past h in the 24-hour system. Here, the 24-hour system represents the hour by an integer between 0 and 23 (inclusive), and the minute by an integer between 0 and 59 (inclusive).
Let A be the tens digit of h, B be the ones digit of h, C be the tens digit of m, and D be the ones digit of m. (Here, if h has only one digit, we consider that it has a leading zero; the same applies to m.)
Then, the clock shows A in its top-left, B in its bottom-left, C in its top-right, and D in its bottom-right.

Takahashi has decided to call a time a confusing time if it satisfies the following condition:

• after swapping the top-right and bottom-left digits on the clock, it still reads a valid time in the 24-hour system.

For example, the clock in Figure 3 shows 20:13. After swapping its top-right and bottom-left digits, it reads 21:03. Thus, 20:13 is a confusing time.
The clock now shows H:M.
Find the next confusing time (including now) in the 24-hour system.

Input

The input is given from Standard Input in the following format:
H M

Output

Let h:m be the answer, where h and m must satisfy $0 \leq h \leq 23$ and $0 \leq m \leq 59$.
Print h and m in the following format:
h m

Your answer is considered correct even if h contains a leading zero to represent it as a 2-digit integer; the same applies to m.

Constraints

• $0 \leq H \leq 23$
• $0 \leq M \leq 59$
• H and M are integers.

Sample Input 1

1 23

Sample Output 1

1 23

1:23 is a confusing time because, after swapping its top-right and bottom-left digits on the clock, it reads 2:13.
Thus, the answer is 1:23.
Your answer is considered correct even if you print 01 23 with a leading zero.

Sample Input 2

19 57

Sample Output 2

20 0

The next confusing time after 19:57 is 20:00.

Sample Input 3

20 40

Sample Output 3

21 0

Note that 24:00 is an invalid notation in the 24-hour system.
