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: "!@#$%^&*()-+".
