How to get the right answer

Hello, Guys

i'm trying to cearte a guessword game by using the following code, but the problem is when i'm typing the correct answer, the program still told me that i'm typing the wrong answer. How can i do to change this? Cheers

GuessedWord = randi([0,4]); 
if GuessedWord < 0 || GuessedWord > 4
    disp("oh you are lcuky and here's what you got !!!!")
    else
switch GuessedWord
    case 0
A = ('oh my god');
fprintf("** ** ***\n ", A);
    case 1 
B = ('this');
fprintf("****\n ", B);
    case 2 
C = ('project');
fprintf("*******\n ", C);
    case 3
D = ('is');
fprintf("**\n ", D);
    case 4
E = ('hard');
fprintf("****\n ", E);
end
end
A = ('Oh My God');
B = ('This');
C = ('Project');
D = ('is');
E = ('hard');
 
guess = [A,B,C,D,E];
while (guess ~= GuessedWord)
guess = input("Guess the word:",'s');
if guess ~= GuessedWord
     fprintf('Sorry mate, Your guess (%s) is wrong!!!!!  \n.' ,guess)
end
if guess == GuessedWord
     fprintf('Congratulations!!! You guess is right (%s). \n', guess)
 end
end
