717 - 1-bit and 2-bit Characters.<p>Easy</p> <p>We have two special characters:</p> <ul> <li>The first character can be represented by one bit <code>0</code>.</li> <li>The second character can be represented by two bits (<code>10</code> or <code>11</code>).</li> </ul> <p>Given a binary array <code>bits</code> that ends with <code>0</code>, return <code>true</code> if the last character must be a one-bit character.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> bits = [1,0,0]</p> <p><strong>Output:</strong> true</p> <p><strong>Explanation:</strong> The only way to decode it is two-bit character and one-bit character. So the last character is one-bit character.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> bits = [1,1,1,0]</p> <p><strong>Output:</strong> false</p> <p><strong>Explanation:</strong> The only way to decode it is two-bit character and two-bit character. So the last character is not one-bit character.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= bits.length <= 1000</code></li> <li><code>bits[i]</code> is either <code>0</code> or <code>1</code>.</li> </ul>
