最近发现的一篇古代预言被认为包含了启示录的确切日期。预言是一个仅由数字和字符“-”组成的字符串。

如果预言中有一个子字符串是日期的记录，格式为“dd-mm-yyyy”，那么我们可以说预言中提到了某个日期。我们可以说，日期的出现次数就是预言中这样的子串的数量。例如，预言“0012-10-2012-10-2012”两次提到日期12-10-2012（第一次是“0012-10-2012-10-2012”，第二次是“00012-10-2012-10-2012”）。

启示录的日期是如此正确，以至于预言中提到它的次数严格大于任何其他正确日期。

如果年份在2013年到2015年之间，月份在1到12之间，并且日期严格大于零且不超过当月的天数，则日期是正确的。请注意，日期的格式是“dd-mm-yyyy”，这意味着如果需要，可以在月或日的数字上加上前导零。也就是说，日期“1-1-2013”没有以“dd-mm-yyyy”的格式记录，因此不符合格式，而日期“01-01-2013”则是正确的。

请注意，2013年至2015年之间的任何一年都不是闰年。

A recently found Ancient Prophesy is believed to contain the exact Apocalypse date. The prophesy is a string that only consists of digits and characters "-".

We'll say that some date is mentioned in the Prophesy if there is a substring in the Prophesy that is the date's record in the format "dd-mm-yyyy". We'll say that the number of the date's occurrences is the number of such substrings in the Prophesy. For example, the Prophesy "0012-10-2012-10-2012" mentions date 12-10-2012 twice (first time as "0012-10-2012-10-2012", second time as "0012-10-2012-10-2012").

The date of the Apocalypse is such correct date that the number of times it is mentioned in the Prophesy is strictly larger than that of any other correct date.

A date is correct if the year lies in the range from 2013 to 2015, the month is from 1 to 12, and the number of the day is strictly more than a zero and doesn't exceed the number of days in the current month. Note that a date is written in the format "dd-mm-yyyy", that means that leading zeroes may be added to the numbers of the months or days if needed. In other words, date "1-1-2013" isn't recorded in the format "dd-mm-yyyy", and date "01-01-2013" is recorded in it.

Notice, that any year between 2013 and 2015 is not a leap year.
