### Test Suite

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

A = 1×4 cell array {'aa'} {'bb'} {'aa'} {'aa'} dups = 1×2 cell array {'aa'} {'bb'}

Assertion failed.

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

A = 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)))

A = 1×3 cell array {'zzz'} {'zzz'} {'zzz'} dups = 1×2 cell array {'zzz'} {'zzz'}

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

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

Assertion failed.

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

A = 0×0 empty cell array dups = 0×0 empty cell array
