"content": "<p>Given an integer <code>x</code>, return <code>true</code> if <code>x</code> is palindrome integer.</p>\n\n<p>An integer is a <strong>palindrome</strong> when it reads the same backward as forward.</p>\n\n<ul>\n\t<li>For example, <code>121</code> is a palindrome while <code>123</code> is not.</li>\n</ul>\n\n<p>&nbsp;</p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> x = 121\n<strong>Output:</strong> true\n<strong>Explanation:</strong> 121 reads as 121 from left to right and from right to left.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> x = -121\n<strong>Output:</strong> false\n<strong>Explanation:</strong> From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome.\n</pre>\n\n<p><strong>Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> x = 10\n<strong>Output:</strong> false\n<strong>Explanation:</strong> Reads 01 from right to left.
