3	Pass	%% x = [1:100 0]; y_correct = [1:100 100]; assert(isequal(bleed_to_the_right(x),y_correct))
4	Pass	%% x = rand(1,1000); x(randi(500,1,50)*2) = 0; y_correct = x; y_correct(~y_correct) = y_correct(find(~y_correct)-1); assert(isequal(bleed_to_the_right(x),y_correct))
5	Pass	%% x = sqrt(1:100); y_correct = floor(x); x(x~=floor(x)) = 0; assert(isequal(bleed_to_the_right(x),y_correct))
