### 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)))

Unrecognized function or variable 's'. Error in duplicates (line 5) if sum([s(:)]) > 1 Error in Test1 (line 3) result = duplicates(strs);

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

Unrecognized function or variable 's'. Error in duplicates (line 5) if sum([s(:)]) > 1 Error in Test2 (line 3) result = duplicates(strs);

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

Unrecognized function or variable 's'. Error in duplicates (line 5) if sum([s(:)]) > 1 Error in Test3 (line 3) result = duplicates(strs);

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

Unrecognized function or variable 's'. Error in duplicates (line 5) if sum([s(:)]) > 1 Error in Test4 (line 3) result = duplicates(strs);

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

Error using strfind PATTERN must be a string scalar or character vector. Error in duplicates (line 4) x = strfind(strs, str); Error in Test5 (line 3) result = duplicates(strs);
