Algorithms

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

<ul>
	<li>It has at least <code>8</code> characters.</li>
	<li>It contains at least one lowercase letter.</li>
	<li>It contains at least one uppercase letter.</li>
	<li>It contains at least one digit.</li>
	<li>It contains at least one special character. The special characters are the characters in the following string: <code>&quot;!@#$%^&amp;*()-+&quot;</code>.</li>
	<li>It does not contain <code>2</code> of the same character in adjacent positions (i.e., <code>&quot;aab&quot;</code> violates this condition, but <code>&quot;aba&quot;</code> does not).</li>
</ul>

Given a string <code>password</code>, return <code>true</code> if it is a strong password. Otherwise, return <code>false</code>.

&nbsp;
Example 1:

<pre>
Input: password = &quot;IloveLe3tcode!&quot;
Output: true
Explanation: The password meets all the requirements. Therefore, we return true.
</pre>

Example 2:

<pre>
Input: password = &quot;Me+You--IsMyDream&quot;
Output: false
Explanation: The password does not contain a digit and also contains 2 of the same character in adjacent positions. Therefore, we return false.
</pre>

Example 3:

<pre>
Input: password = &quot;1aB!&quot;
Output: false
Explanation: The password does not meet the length requirement. Therefore, we return false.</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= password.length &lt;= 100</code></li>
	<li><code>password</code> consists of letters, digits, and special characters: <code>&quot;!@#$%^&amp;*()-+&quot;</code>.</li>
</ul>

String

如果一个密码满足以下所有条件，我们称它是一个 强&nbsp;密码：

<ul>
	<li>它有至少 <code>8</code>&nbsp;个字符。</li>
	<li>至少包含 一个小写英文&nbsp;字母。</li>
	<li>至少包含 一个大写英文&nbsp;字母。</li>
	<li>至少包含 一个数字&nbsp;。</li>
	<li>至少包含 一个特殊字符&nbsp;。特殊字符为：<code>"!@#$%^&amp;*()-+"</code>&nbsp;中的一个。</li>
	<li>它 不&nbsp;包含&nbsp;<code>2</code>&nbsp;个连续相同的字符（比方说&nbsp;<code>"aab"</code>&nbsp;不符合该条件，但是&nbsp;<code>"aba"</code>&nbsp;符合该条件）。</li>
</ul>

给你一个字符串&nbsp;<code>password</code>&nbsp;，如果它是一个&nbsp;强&nbsp;密码，返回&nbsp;<code>true</code>，否则返回&nbsp;<code>false</code>&nbsp;。

&nbsp;

示例 1：

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

示例 2：

<pre>输入：password = "Me+You--IsMyDream"
输出：false
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 。
</pre>

示例 3：

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

&nbsp;

提示：

<ul>
	<li><code>1 &lt;= password.length &lt;= 100</code></li>
	<li><code>password</code>&nbsp;包含字母，数字和&nbsp;<code>"!@#$%^&amp;*()-+"</code>&nbsp;这些特殊字符。</li>
</ul>
