### Test Suite

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)))

dups = 1×4 cell array 'aa' 'bb' 'aa' 'aa' dups = cell 'aa'

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

dups = 1×3 cell array '10' '11' '12' dups = 0×0 empty cell array

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

dups = 1×3 cell array 'zzz' 'zzz' 'zzz' dups = 0×0 empty cell array

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

dups = 1×6 cell array 'a' 'b' 'c' 'b' 'd' 'c' dups = 1×2 cell array 'b' 'c'

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

dups = 0×0 empty cell array
