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)))

ia = 1×2 cell array {'aa'} {'bb'} ib = 3 4

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

ia = 1×3 cell array {'10'} {'11'} {'12'} ib = 1 2 3

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

ia = 1×1 cell array {'zzz'} ib = 3

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

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