Password Strength

Description

Build a password strength checker in React that evaluates and displays the strength level of a user's password. The goal of this problem is to create a password strength checker that evaluates the strength of a given password based on specific criteria. The password is considered strong if it meets all or 4 of the following rules:

1. Length: At least 8 characters.
2. Uppercase Letters: At least one uppercase letter (A-Z).
3. Lowercase Letters: At least one lowercase letter (a-z).
4. Numbers: At least one digit (0-9).
5. Special Characters: At least one special character (e.g., @, #, $, %, etc.).

Strength Levels:

• Level 1: Password meets only 1 of the 5 criteria
• Level 2: Password meets 2 or 3 of the 5 criteria
• Level 3: Password meets 4 or 5 of the 5 criteria
• If the password does not meet any criteria, it's considered a weak password and the function returns " Weak Password ".

Important Instructions

• Define a helper function called checkPasswordStrength inside the same file.
• Export that helper function so it can be tested separately
• The UI should have:
  • An input field for password
  • A button to check strength
  • A strength result displayed after clicking

Example Inputs & Outputs

Example 1:

• Input: ""
• Output: "Weak Password"
• Explanation: The password is empty, so it doesn't meet any criteria.

Example 1:

• Input: "abc123"
• Output: "Level 1"
• Explanation: The password contains lowercase letters and numbers but doesn't meet the other criteria (uppercase, special character).

Example 2:

• Input: "abc123ABC"
• Output: "Level 2"
• Explanation: The password meets 3 criteria: length (>=8), lowercase, and numbers, but lacks a special character.

Example 3:

• Input: "Abc12345"
• Output: "Level 2"
• Explanation: The password meets 4 criteria: length, uppercase, lowercase, and numbers, but lacks a special character.

Example 4:

• Input: "Abc@1234"
• Output: "Level 3"
• Explanation: The password meets all 5 criteria: length (>=8), uppercase, lowercase, numbers, and special character.
