Pass

x = [1 2 5 2 2 7 8 3 3 1 3 8 8 8]; y_correct = [2 3]; assert(isequal(threeTimes(x),y_correct))

y = 1 2 3 5 7 8 t = 1×6 logical array 0 1 1 0 0 0 y = 2 3

Pass

x = [1 1 1]; y_correct = [1]; assert(isequal(threeTimes(x),y_correct))

y = 1 t = logical 1 y = 1

Pass

x = [5 10 -3 10 -3 11 -3 5 5 7]; y_correct = [-3 5]; assert(isequal(threeTimes(x),y_correct))

y = -3 5 7 10 11 t = 1×5 logical array 1 1 0 0 0 y = -3 5
