Test Status Code Input and Output
1   Pass
strs = {'aa','bb','aa','aa'}; correct = {'aa'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

a = 3 1 b = 1×2 cell array {'aa'} {'bb'} ans = 1×1 cell array {'aa'}

2   Pass
strs = {'10','11','12'}; correct = {}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

a = 1 1 1 b = 1×3 cell array {'10'} {'11'} {'12'} ans = 1×0 empty cell array

3   Pass
strs = {'zzz','zzz','zzz'}; correct = {'zzz'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

a = 3 b = 1×1 cell array {'zzz'} ans = 1×1 cell array {'zzz'}

4   Pass
strs = {'a','b','c','b','d','c'}; correct = {'b','c'}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

a = 1 2 2 1 b = 1×4 cell array {'a'} {'b'} {'c'} {'d'} ans = 1×2 cell array {'b'} {'c'}

5   Pass
strs = {}; correct = {}; result = duplicates(strs); assert(isempty(setdiff(result,correct)) & isempty(setdiff(correct,result)))

a = 1×0 empty double row vector b = 1×0 empty cell array ans = 1×0 empty cell array
