Description
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
