% Game_Of_Nim_UC_errors.m – John Friendly – 10/28/2013

% Description: This program will allow a user to play against

% the computer in a game of Nim.

% Usage: Game_Of_Nim_UC_errors;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% variables used

% numbOfBears          current number of Bears

% playerBears          number of Bears selected by the computer or the player

% compSmartMode         true = smart mode, false = stupid mode

% turn             true = computer turn, false = player turn

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% SETUP:

% determine the initial number of bearcats (10 <= numbOfBears <= 100), who 

% will go first(turn = true -> computer), and whether the computer will 

% play in smart mode (compSmartMode = true -> smart mode)

% seed the random number generator with the current time

rng(‘shuffle’);

% generate the random number of Bears between 10 and 100

numbOfBears = randi(1)*90+10;

there are errors in this game can u fix them and make it work please.

 Prior to beginning work on this discussion, read Chapters 15 and 17 in the course text, as well as the article titled “Ethical Considerations in Geriatric Neuropsychology,” and view Dr. Chung’s Ted Talk, Autism – what we know (and what we don’t know yet) (Links to an external site.)Links to an external site.. Pick a disorder of brain development (e.g., onset during childhood) or aging (e.g., dementia due to a neurodegenerative disorder). Explain the symptoms, how the diagnosis is made (e.g., findings on brain imaging, laboratory testing, etc.), the neurobiological basis for the disorder (e.g., CNS structures involved and neurotransmitters), and current treatment options (including mechanism of action for any drug therapies). You must use a minimum of two peer-reviewed articles in your discussion to support your statements.
