A password is said to be strong if it satisfies all the following criteria:

\n\n\n\n

Given a string password, return true if it is a strong password. Otherwise, return false.

\n\n

 

\n

Example 1:

\n\n
\nInput: password = "IloveLe3tcode!"\nOutput: true\nExplanation: The password meets all the requirements. Therefore, we return true.\n
\n\n

Example 2:

\n\n
\nInput: password = "Me+You--IsMyDream"\nOutput: false\nExplanation: The password does not contain a digit and also contains 2 of the same character in adjacent positions. Therefore, we return false.\n
\n\n

Example 3:

\n\n
\nInput: password = "1aB!"\nOutput: false\nExplanation: The password does not meet the length requirement. Therefore, we return false.

如果一个密码满足以下所有条件,我们称它是一个  密码:

\n\n\n\n

给你一个字符串 password ,如果它是一个  密码,返回 true,否则返回 false 。

\n\n

 

\n\n

示例 1:

\n\n
输入:password = \"IloveLe3tcode!\"\n输出:true\n解释:密码满足所有的要求,所以我们返回 true 。\n
\n\n

示例 2:

\n\n
输入:password = \"Me+You--IsMyDream\"\n输出:false\n解释:密码不包含数字,且包含 2 个连续相同的字符。所以我们返回 false 。\n
\n\n

示例 3:

\n\n
输入:password = \"1aB!\"\n输出:false\n解释:密码不符合长度要求。所以我们返回 false 。
