A Date in Binary

Easy

The string day is a date in yyyy-mm-dd format, such as "2024-07-15". Write the year, the month and the day in binary, each without leading zeros, and join them with hyphens in the same order: year, month, day. Return the resulting string.

Example 1

day="2024-07-15" → '11111101000-111-1111'

2024 = 11111101000₂, 7 = 111₂, 15 = 1111₂.

Example 2

day="1961-04-12" → '11110101001-100-1100'

The month's leading zero disappears: 04 becomes just 100.

Constraints

len(day) = 10
day[4] and day[7] are hyphens and every other character is a digit
day is a real calendar date from January 1, 1900 to December 31, 2100 inclusive
