"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",
"translatedTitle": "比较版本号",
"translatedContent": "<p>给你两个版本号 <code>version1</code> 和 <code>version2</code> ，请你比较它们。</p>\n\n<p>版本号由一个或多个修订号组成，各修订号由一个 <code>'.'</code> 连接。每个修订号由 <strong>多位数字</strong> 组成，可能包含 <strong>前导零</strong> 。每个版本号至少包含一个字符。修订号从左到右编号，下标从 0 开始，最左边的修订号下标为 0 ，下一个修订号下标为 1 ，以此类推。例如，<code>2.5.33</code> 和 <code>0.1</code> 都是有效的版本号。</p>\n\n<p>比较版本号时，请按从左到右的顺序依次比较它们的修订号。比较修订号时，只需比较 <strong>忽略任何前导零后的整数值</strong> 。也就是说，修订号 <code>1</code> 和修订号 <code>001</code> <strong>相等 </strong>。如果版本号没有指定某个下标处的修订号，则该修订号视为 <code>0</code> 。例如，版本 <code>1.0</code> 小于版本 <code>1.1</code> ，因为它们下标为 <code>0</code> 的修订号相同，而下标为 <code>1</code> 的修订号分别为 <code>0</code> 和 <code>1</code> ，<code>0 < 1</code> 。</p>\n\n<p>返回规则如下：</p>\n\n<ul>\n\t<li>如果 <code><em>version1 </em>> <em>version2</em></code> 返回 <code>1</code>，</li>\n\t<li>如果 <code><em>version1 </em>< <em>version2</em></code> 返回 <code>-1</code>，</li>\n\t<li>除此之外返回 <code>0</code>。</li>\n</ul>\n\n<p> </p>\n\n<p><strong>示例 1：</strong></p>\n\n<pre>\n<strong>输入：</strong>version1 = \"1.01\", version2 = \"1.001\"\n<strong>输出：</strong>0\n<strong>解释：</strong>忽略前导零，\"01\" 和 \"001\" 都表示相同的整数 \"1\"\n</pre>\n\n<p><strong>示例 2：</strong></p>\n\n<pre>\n<strong>输入：</strong>version1 = \"1.0\", version2 = \"1.0.0\"\n<strong>输出：</strong>0\n<strong>解释：</strong>version1 没有指定下标为 2 的修订号，即视为 \"0\"\n</pre>\n\n<p><strong>示例 3：</strong></p>\n\n<pre>\n<strong>输入：</strong>version1 = \"0.1\", version2 = \"1.1\"\n<strong>输出：</strong>-1\n<strong>解释：</strong>version1 中下标为 0 的修订号是 \"0\"，version2 中下标为 0 的修订号是 \"1\" 。0 < 1，所以 version1 < version2\n</pre>\n\n<p> </p>\n\n<p><strong>提示：</strong></p>\n\n<ul>\n\t<li><code>1 <= version1.length, version2.length <= 500</code></li>\n\t<li><code>version1</code> 和 <code>version2</code> 仅包含数字和 <code>'.'</code></li>\n\t<li><code>version1</code> 和 <code>version2</code> 都是 <strong>有效版本号</strong></li>\n\t<li><code>version1</code> 和 <code>version2</code> 的所有修订号都可以存储在 <strong>32 位整数</strong> 中</li>\n</ul>\n",
