    717 - 1-bit and 2-bit Characters.

    Easy

    We have two special characters:

    • The first character can be represented by one bit 0.

    • The second character can be represented by two bits (10 or 11).

    Given a binary array bits that ends with 0, return true if the last character must be a one-bit character.

    Example 1:

    Input: bits = 1,0,0

    Output: true

    Explanation: The only way to decode it is two-bit character and one-bit character. So the last character is one-bit character.

    Example 2:

    Input: bits = 1,1,1,0

    Output: false

    Explanation: The only way to decode it is two-bit character and two-bit character. So the last character is not one-bit character.

    Constraints:

    • 1 <= bits.length <= 1000

    • bits[i] is either 0 or 1.
