Description
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.
