Guess number game

1. Generate random integer (0, 100)
2. Prompt the user to enter the guessed number in the console
3. In comparison, when the user input is large, the prompt is too large
4. When the user input is too small, the prompt is too small
5. When the user input is correct, the prompt is correct after N times, too smart
6. The user guesses up to 5 times. If the guess is not correct within 5 times, the prompt is too stupid and the game is over
7. After success or failure, prompt the user whether to continue, enter: yes, y, Y to continue, regenerate random numbers, let the user guess
