681. Next Closest Time π
Description
Given a time
represented in the format "HH:MM"
, form the next closest time by reusing the current digits. There is no limit on how many times a digit can be reused.
You may assume the given input string is always valid. For example, "01:34"
, "12:09"
are all valid. "1:34"
, "12:9"
are all invalid.
Example 1:
Input: time = "19:34" Output: "19:39" Explanation: The next closest time choosing from digits 1, 9, 3, 4, is 19:39, which occurs 5 minutes later. It is not 19:33, because this occurs 23 hours and 59 minutes later.
Example 2:
Input: time = "23:59" Output: "22:22" Explanation: The next closest time choosing from digits 2, 3, 5, 9, is 22:22. It may be assumed that the returned time is next day's time since it is smaller than the input time numerically.
Constraints:
time.length == 5
time
is a valid time in the form"HH:MM"
.0 <= HH < 24
0 <= MM < 60
