<p>You are given a binary string <code>s</code>.</p>

<p>Return the number of <span data-keyword="substring-nonempty">substrings</span> with <strong>dominant</strong> ones.</p>

<p>A string has <strong>dominant</strong> ones if the number of ones in the string is <strong>greater than or equal to</strong> the <strong>square</strong> of the number of zeros in the string.</p>

<p><strong>Explanation:</strong></p>

<p>The substrings with <strong>non-dominant</strong> ones are shown in the table below.</p>

<p>Since there are 21 substrings total and 5 of them have non-dominant ones, it follows that there are 16 substrings with dominant ones.</p>
