Given a string input containing password characters, the task is to check the strength of the password.
The strength of the password is when you are told whether the password is easy to guess or crack. The strength should vary from weak, moderate, and strong.
The password length must be at least8characters.
It must contain1lowercase.
It must contain1uppercase
It must contain a digit
It must contain a special character, such as: !@#$%^&*> < , .+ =-
is like having a password "w3codebox”is easy to guess, so we can conclude that the password "weak" he provided is because it only contains lowercase letters, while the password "w3codebox @ 863!” which has both uppercase and lowercase letters, numbers, and special characters, and has robustness, and its length is greater than8characters, therefore meeting all the conditions that make the password stronger.
If some passwords meet more than half of the characteristics of a strong password, then we will consider the password to be moderate. Like the password "w3codebox12It will be considered moderate because it contains lowercase letters, a digit, and its length is greater than8characters.
Input: w3codebox!@12 Output: Password strength:-Strong Explanation: Password has 1 lowercase, 1 uppercase, 1 special character, more than 8 characters long and a digit, hence the password is strong. Input: w3codebox Output: Password strength:-Weak
The method we will use to solve the given problem-
Output the string as the password.
Check if all the factors can be used to determine the strength of the password.
Print the strength of the password based on the factors.

Output result
Strength of password:-Moderate
