2299\. Strong Password Checker II

Easy

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

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

Given a string `password`, return `true` _if it is a **strong** password_. Otherwise, return `false`.

**Example 1:**

**Input:** password = "IloveLe3tcode!"

**Output:** true

**Explanation:** The password meets all the requirements. Therefore, we return true. 

**Example 2:**

**Input:** password = "Me+You--IsMyDream"

**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. 

**Example 3:**

**Input:** password = "1aB!"

**Output:** false

**Explanation:** The password does not meet the length requirement. Therefore, we return false.

**Constraints:**

*   `1 <= password.length <= 100`
*   `password` consists of letters, digits, and special characters: `"!@#$%^&*()-+"`.
