1. Give a brief description of how the code below works.
   Use plain, accessible language and avoid repeating
   the exact statements from the code. Aim to write at
   least 3 sentences.
   
   The code asks players to input their name. Then, it outputs sentence and their name.
   The computer desides a number of the answer, then, the code asks players to guess and input a number 1 to 10.
   The computer culculate whether the number that player input was same or different with the answer.
   If the number is collect, it shows correct. If it is wrong, the code shows the guessing number was higher or lower.
   
2. Make a modification to the code in some place that changes the game
   in some interesting way. This cannot be as simple as changing the
   MINIMUM or one of the printed messages, but make enough changes and
   they can add up. You might allow the player to play more rounds after
   the first one, or completely change all the messages to have a pirate
   theme, or make it so the player can specify the maximum number.
   Describe your change here clearly and explain why you thought it was
   interesting.
   
   I added 'level 2' on this game and changed maximum and minimum numbers.
   As a result, the difficulity level became high so players probably enjoy it.
