### 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)))

C = 1×2 cell array 'aa' 'bb' ia = 1 2 ib = 1 2 1 1 C = cell 'aa'

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

C = 1×3 cell array '10' '11' '12' ia = 1 2 3 ib = 1 2 3 C = 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)))

C = cell 'zzz' ia = 1 ib = 1 1 1 C = cell '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)))

C = 1×4 cell array 'a' 'b' 'c' 'd' ia = 1 2 3 5 ib = 1 2 3 2 4 3 C = 1×2 cell array 'b' 'c'

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

C = 0×1 empty cell array ia = 0×1 empty double column vector ib = 0×1 empty double column vector C = 0×1 empty cell array
