Maximum Time

You are given a string that represents time in the format hh:mm. Some of the digits are blank (represented by ‘?’). Fill in ‘?’ such that the time represented by this string is the maximum possible. Maximum time: 23:59, minimum time: 00:00. You can assume that the input string is always valid.

For Example :

If the given input string is 1?:?8.
We can replace the first ‘?’ with 9 and second with 5 to get the maximum time of 19:58.

Input Format :

 The first line contains a single integer ‘T’ denoting the number of test cases Then each test case follows.
 The first line of each test case contains a string in the format of ‘hh:mm’.

Output Format :

 For each test case print a string denoting the maximum possible time after replacing the ‘?’ marks with numbers..

Output for each test case will be printed in a separate line.

Note :

You are not required to print anything; it has already been taken care of. Just implement the function.

Constraints :

1 <= T <= 1000     
|S| = 5

Time limit: 1 sec
