Test Status Code Input and Output
1   Fail
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))

count = 2 3 3 1 1 4 val = 1×6 cell array {'1'} {'2'} {'3'} {'5'} {'7'} {'8'} val = 1 2 3 5 7 8

Assertion failed.

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

count = 3 val = 1×1 cell array {'1'} val = 1

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

count = 3 3 1 2 1 val = 1×5 cell array {'-3'} {'5'} {'7'} {'10'} {'11'} val = -3 5 7 10 11

Assertion failed.
