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.
