respond equal a character ?

hi all,

I did it,

accept=input('do you want to play again, Yes(Y,y), No(N,n); \n','s');

while accept~='Y'||accept~='y'||accept~='N'||accept~='n'
    
accept=input('do you want to play again, Yes(Y,y), No(N,n); \n','s');

end

and it is not working. I couldn't save quastion of while loop can anyone help me ?

Given A~=B, can you give a value of X which will make this statement false?:

X~=A || X~=B

Use strcmp() or strcmpi() or ismember()

Using ~= together with "||" will fail if the user enters more than one character.
