926 - Flip String to Monotone Increasing.<p>Medium</p> <p>A binary string is monotone increasing if it consists of some number of <code>0</code>&rsquo;s (possibly none), followed by some number of <code>1</code>&rsquo;s (also possibly none).</p> <p>You are given a binary string <code>s</code>. You can flip <code>s[i]</code> changing it from <code>0</code> to <code>1</code> or from <code>1</code> to <code>0</code>.</p> <p>Return <em>the minimum number of flips to make</em> <code>s</code> <em>monotone increasing</em>.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> s = &ldquo;00110&rdquo;</p> <p><strong>Output:</strong> 1</p> <p><strong>Explanation:</strong> We flip the last digit to get 00111.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> s = &ldquo;010110&rdquo;</p> <p><strong>Output:</strong> 2</p> <p><strong>Explanation:</strong> We flip to get 011111, or alternatively 000111.</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> s = &ldquo;00011000&rdquo;</p> <p><strong>Output:</strong> 2</p> <p><strong>Explanation:</strong> We flip to get 00000000.</p> <p><strong>Constraints:</strong></p> <ul> <li><code>1 <= s.length <= 10⁵</code></li> <li><code>s[i]</code> is either <code>'0'</code> or <code>'1'</code>.</li> </ul>
