Implement Difficulty Levels

The code currently has placeholders for setting the bounds and max attempts for each difficulty level (Easy, Medium, Hard). Implement the correct values for these difficulty levels:

Easy: Range 1-10, 5 attempts.
Medium: Range 1-50, 7 attempts.
Hard: Range 1-100, 10 attempts.

Acceptance Criteria:

Update the switch statement to set lowerBound, upperBound, and maxAttempts for each case.

Find the switch statement for difficulty levels in the codebase, likely in a main game logic file. Update the 'Easy', 'Medium', and 'Hard' cases to set lowerBound, upperBound, and maxAttempts as specified. Compile and run the program to test each difficulty level.
