Solved
Easy
Topics

You are given a string date representing a Gregorian calendar date in the yyyy-mm-dd format.
date can be written in its binary representation obtained by converting year, month, and day to their binary representations without any leading zeroes and writing them down in year-month-day format.
Return the binary representation of date.

Example 1:
Input: date = "2080-02-29"
Output: "100000100000-10-11101"
Explanation:
100000100000, 10, and 11101 are the binary representations of 2080, 02, and 29 respectively.

Example 2:
Input: date = "1900-01-01"
Output: "11101101100-1-1"
Explanation:
11101101100, 1, and 1 are the binary representations of 1900, 1, and 1 respectively.

Constraints:
    date.length == 10
    date[4] == date[7] == '-', and all other date[i]'s are digits.
    The input is generated such that date represents a valid Gregorian calendar date between Jan 1st, 1900 and Dec 31st, 2100 (both inclusive).
