"content": "<p>Given two version numbers, <code>version1</code> and <code>version2</code>, compare them.</p>\n\n<ul>\n</ul>\n\n<p>Version numbers consist of <strong>one or more revisions</strong> joined by a dot <code>'.'</code>. Each revision consists of <strong>digits</strong> and may contain leading <strong>zeros</strong>. Every revision contains <strong>at least one character</strong>. Revisions are <strong>0-indexed from left to right</strong>, with the leftmost revision being revision 0, the next revision being revision 1, and so on. For example <code>2.5.33</code> and <code>0.1</code> are valid version numbers.</p>\n\n<p>To compare version numbers, compare their revisions in <strong>left-to-right order</strong>. Revisions are compared using their <strong>integer value ignoring any leading zeros</strong>. This means that revisions <code>1</code> and <code>001</code> are considered <strong>equal</strong>. If a version number does not specify a revision at an index, then <strong>treat the revision as <code>0</code></strong>. For example, version <code>1.0</code> is less than version <code>1.1</code> because their revision 0s are the same, but their revision 1s are <code>0</code> and <code>1</code> respectively, and <code>0 < 1</code>.</p>\n\n<p><em>Return the following:</em></p>\n\n<ul>\n\t<li>If <code>version1 < version2</code>, return <code>-1</code>.</li>\n\t<li>If <code>version1 > version2</code>, return <code>1</code>.</li>\n\t<li>Otherwise, return <code>0</code>.</li>\n</ul>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> version1 = "1.01", version2 = "1.001"\n<strong>Output:</strong> 0\n<strong>Explanation:</strong> Ignoring leading zeroes, both "01" and "001" represent the same integer "1".\n</pre>\n\n<p><strong class=\"example\">Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> version1 = "1.0", version2 = "1.0.0"\n<strong>Output:</strong> 0\n<strong>Explanation:</strong> version1 does not specify revision 2, which means it is treated as "0".\n</pre>\n\n<p><strong class=\"example\">Example 3:</strong></p>\n\n<pre>\n<strong>Input:</strong> version1 = "0.1", version2 = "1.1"\n<strong>Output:</strong> -1\n<strong>Explanation:</strong> version1's revision 0 is "0", while version2's revision 0 is "1". 0 < 1, so version1 < version2.\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= version1.length, version2.length <= 500</code></li>\n\t<li><code>version1</code> and <code>version2</code> only contain digits and <code>'.'</code>.</li>\n\t<li><code>version1</code> and <code>version2</code> <strong>are valid version numbers</strong>.</li>\n\t<li>All the given revisions in <code>version1</code> and <code>version2</code> can be stored in a <strong>32-bit integer</strong>.</li>\n</ul>\n",
