Days Between Two Dates

Easy

You are given two dates first and second in the YYYY-MM-DD format. Return the number of days between them. The dates may come in either order; the answer is never negative. Mind the leap years: a year is a leap year if it is divisible by 4, except years divisible by 100 but not by 400.

Example 1

first="2024-02-27", second="2024-03-02" → 4

2024 is a leap year, so February has 29 days: from Feb 27 to Mar 2 is four days.

Example 2

first="2031-01-10", second="2030-12-25" → 16

The order of the dates does not matter: from Dec 25 to Jan 10 is 16 days.

Example 3

first="1999-07-04", second="1999-07-04" → 0

Constraints

Both dates exist in the calendar
Years are between 1971 and 2100
