### 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 ic = 1 2 1 1

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 ic = 1 2 3

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

c = 1×1 cell array {'zzz'} ia = 1 ic = 1 1 1

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 ic = 1 2 3 2 4 3

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 ic = 0×1 empty double column vector
