# You are given a date in the format YYYY-MM-DD.
# Write a script to convert it into binary date.
# Example 1 Input: $date = "2025-07-26"
# Output: "11111101001-111-11010"
# Example 2 Input: $date = "2000-02-02"
# Output: "11111010000-10-10"
# Example 3 Input: $date = "2024-12-31"
# Output: "11111101000-1100-11111"
