class and Control: Password Strength Check

In this problem, you will create a program that receives a password length and special character presence, calls multiple check methods of a PasswordChecker class in sequence to evaluate password strength, and displays the result to standard output.

Learning Objective: Control program flow by calling class methods in sequence

Create PasswordChecker class to determine strength from password length and special character presence. Learn how to progress validation step by step by calling multiple check methods in sequence.

Understanding with Concrete Examples

Example 1: Strongest Password

Input:
15
1

Output:
Password Strength:
Length: 15characters
Special: Yes
Strength: Very Strong
```java

### Example 2: Medium Strength Password
```java
Input:
10
1

Output:
Password Strength:
Length: 10characters
Special: Yes
Strength: Medium
```java

### Example 3: Long But No Special (Boundary)
```java
Input:
12
0

Output:
Password Strength:
Length: 12characters
Special: No
Strength: Strong
```java

## Input
Line 1: Password length (integer, 1-50)
Line 2: Special character presence (integer, 0=no/1=yes)

## Output
```java
Password Strength:
Length: [length]characters
Special: [presence]
Strength: [strength]
```java

Strength determination:
- 12 or more chars and special chars: Very Strong
- 12 or more chars: Strong
- 8 or more chars and special chars: Medium
- Others: Weak
