In other words, <code>val ^ first<sub>i</sub> == second<sub>i</sub></code>.</p>\n\n<p>The answer to the <code>i<sup>th</sup></code> query is the endpoints (<strong>0-indexed</strong>) of the substring <code>[left<sub>i</sub>, right<sub>i</sub>]</code> or <code>[-1, -1]</code> if no such substring exists. If there are multiple answers, choose the one with the <strong>minimum</strong> <code>left<sub>i</sub></code>.</p>\n\n<p><em>Return an array</em> <code>ans</code> <em>where</em> <code>ans[i] = [left<sub>i</sub>, right<sub>i</sub>]</code> <em>is the answer to the</em> <code>i<sup>th</sup></code> <em>query.</em></p>\n\n<p>A <strong>substring</strong> is a contiguous non-empty sequence of characters within a string.</p>\n\n<p>&nbsp;</p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;101101&quot;, queries = [[0,5],[1,2]]\n<strong>Output:</strong> [[0,2],[2,3]]\n<strong>Explanation:</strong> For the first query the substring in range <code>[0,2]</code> is <strong>&quot;101&quot;</strong> which has a decimal value of <strong><code>5</code></strong>, and <strong><code>5 ^ 0 = 5</code></strong>, hence the answer to the first query is <code>[0,2]</code>. In the second query, the substring in range <code>[2,3]</code> is <strong>&quot;11&quot;,</strong> and has a decimal value of <strong>3</strong>, and <strong>3<code> ^ 1 = 2</code></strong>.&nbsp;So, <code>[2,3]</code> is returned for the second query. \n\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;0101&quot;, queries = [[12,8]]\n<strong>Output:</strong> [[-1,-1]]\n<strong>Explanation:</strong> In this example there is no substring that answers the query, hence <code>[-1,-1] is returned</code>.\n</pre>\n\n<p><strong class=\"example\">Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;1&quot;, queries = [[4,5]]\n<strong>Output:</strong> [[0,0]]\n<strong>Explanation:</strong> For this example, the substring in range <code>[0,0]</code> has a decimal value of <strong><code>1</code></strong>, and <strong><code>1 ^ 4 = 5</code></strong>.
