Sentinel:

Sentinel is a special value that is used to stop the sequence of series when there is no indication of explicit size.

  • • It is also called as “flag value” or “dummy value” created in the algorithm to terminate the program.
  • • The sentinel value must be a distinct value from the other data values, so that it is guaranteed to end the data.
    • ○ For example: “null character” is used to end the null terminated string and a “negative integer” is used to indicate the end of sequence for non-negative integers.

ASSIGNMENT BRIEF Introduction Roulette is a popular casino game named after the French word for 'little wheel'.

check_game_over(): as the name suggests, this function should check to see if the game is over (if one side has no stones left in all of its pockets). It takes as an argument the game board and should return True if the game is over and False otherwise.
