Strength Checker for Password Systems: For a given password system, calculate the search space for a general user and a lazy user. Suppose only 11 special characters can be input. Program with any language. Input (by the evaluator): 1st line: number of characters 2nd line: numbers allowed [Y/NJ? must be included [Y/NJ? 3rd line: letters allowed [Y/NJ? case sensitive [Y/NJ? must be included [Y/NJ? 4th line: special character allowed [Y/NJ? must be included [Y/NJ? Output: 1st line: The search space for a general user is (). 2nd line: The search space for a lazy user is 0. Example: Input: 6 YY YYY YY Output: The search space for a general user is 1.43*10^11. The search space for a lazy user is 2.68*10^9.

Strength Checker for Password Systems:
For a given password system, calculate the search space for a general user and a lazy user. Suppose only 11 special characters can be input. Program with any language.
Input (by the evaluator):
1st line: number of characters
2nd line: numbers allowed [Y/N]? must be included [Y/N]?
3rd line: letters allowed [Y/N]? case sensitive [Y/N]? must be included [Y/N]?
4th line: special character allowed [Y/NJ? must be included [Y/N]?
Output:
1st line: The search space for a general user is ().
2nd line: The search space for a lazy user is (].
Example:
Input:
6
YY
YYY
YY
Output:
The search space for a general user is 1.43*10^11.
The search space for a lazy user is 2.68*10^9.
