            "content": "<p>Implement the <code>myAtoi(string s)</code> function, which converts a string to a 32-bit signed integer (similar to C/C++&#39;s <code>atoi</code> function).</p>\n\n<p>The algorithm for <code>myAtoi(string s)</code> is as follows:</p>\n\n<ol>\n\t<li>Read in and ignore any leading whitespace.</li>\n\t<li>Check if the next character (if not already at the end of the string) is <code>&#39;-&#39;</code> or <code>&#39;+&#39;</code>. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present.</li>\n\t<li>Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored.</li>\n\t<li>Convert these digits into an integer (i.e. <code>&quot;123&quot; -&gt; 123</code>, <code>&quot;0032&quot; -&gt; 32</code>). If no digits were read, then the integer is <code>0</code>. Change the sign as necessary (from step 2).</li>\n\t<li>If the integer is out of the 32-bit signed integer range <code>[-2<sup>31</sup>, 2<sup>31</sup> - 1]</code>, then clamp the integer so that it remains in the range. Specifically, integers less than <code>-2<sup>31</sup></code> should be clamped to <code>-2<sup>31</sup></code>, and integers greater than <code>2<sup>31</sup> - 1</code> should be clamped to <code>2<sup>31</sup> - 1</code>.</li>\n\t<li>Return the integer as the final result.</li>\n</ol>\n\n<p><strong>Note:</strong></p>\n\n<ul>\n\t<li>Only the space character <code>&#39; &#39;</code> is considered a whitespace character.</li>\n\t<li><strong>Do not ignore</strong> any characters other than the leading whitespace or the rest of the string after the digits.</li>\n</ul>\n\n<p>&nbsp;</p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;42&quot;\n<strong>Output:</strong> 42\n<strong>Explanation:</strong> The underlined characters are what is read in, the caret is the current reader position.\nStep 1: &quot;42&quot; (no characters read because there is no leading whitespace)\n         ^\nStep 2: &quot;42&quot; (no characters read because there is neither a &#39;-&#39; nor &#39;+&#39;)\n         ^\nStep 3: &quot;<u>42</u>&quot; (&quot;42&quot; is read in)\n           ^\nThe parsed integer is 42.\nSince 42 is in the range [-2<sup>31</sup>, 2<sup>31</sup> - 1], the final result is 42.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;   -42&quot;\n<strong>Output:</strong> -42\n<strong>Explanation:</strong>\nStep 1: &quot;<u>   </u>-42&quot; (leading whitespace is read and ignored)\n            ^\nStep 2: &quot;   <u>-</u>42&quot; (&#39;-&#39; is read, so the result should be negative)\n             ^\nStep 3: &quot;   -<u>42</u>&quot; (&quot;42&quot; is read in)\n               ^\nThe parsed integer is -42.\nSince -42 is in the range [-2<sup>31</sup>, 2<sup>31</sup> - 1], the final result is -42.\n</pre>\n\n<p><strong>Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> s = &quot;4193 with words&quot;\n<strong>Output:</strong> 4193\n<strong>Explanation:</strong>\nStep 1: &quot;4193 with words&quot; (no characters read because there is no leading whitespace)\n         ^\nStep 2: &quot;4193 with words&quot; (no characters read because there is neither a &#39;-&#39; nor &#39;+&#39;)\n         ^\nStep 3: &quot;<u>4193</u> with words&quot; (&quot;4193&quot; is read in; reading stops because the next character is a non-digit)\n             ^\nThe parsed integer is 4193.\nSince 4193 is in the range [-2<sup>31</sup>, 2<sup>31</sup> - 1], the final result is 4193.\n</pre>\n\n<p>&nbsp;</p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>0 &lt;= s.length &lt;= 200</code></li>\n\t<li><code>s</code> consists of English letters (lower-case and upper-case), digits (<code>0-9</code>), <code>&#39; &#39;</code>, <code>&#39;+&#39;</code>, <code>&#39;-&#39;</code>, and <code>&#39;.&#39;</code>.</li>\n</ul>\n",
