Test Status Code Input and Output
1   Fail

input_text = 'bla, bla, bla' m = 'abcdefghijklmnopqrstuvwxyz'

Error using hist (line 79) Input arguments must be numeric or a categorical array. Error in letters_occurrence (line 4) occurrence=hist(input_text,unique(input_text)) Error in Test1 (line 3) assert(isequal(letters_occurrence(input_text),occurrence_correct))

2   Fail
input_text = {'King Richard: A horse, a horse! My kingdom for a horse!'}; occurrence_correct = [4 0 1 2 3 1 2 4 3 0 2 0 2 2 5 0 0 6 3 0 0 0 0 0 1 0]; assert(isequal(letters_occurrence(input_text),occurrence_correct))

input_text = 1×1 cell array {'king richard: a horse, a horse! my kingdom for a horse!'} m = 'abcdefghijklmnopqrstuvwxyz'

Error using hist (line 79) Input arguments must be numeric or a categorical array. Error in letters_occurrence (line 4) occurrence=hist(input_text,unique(input_text)) Error in Test2 (line 3) assert(isequal(letters_occurrence(input_text),occurrence_correct))

Error using hist (line 79) Input arguments must be numeric or a categorical array. Error in letters_occurrence (line 4) occurrence=hist(input_text,unique(input_text)) Error in Test3 (line 3) assert(isequal(letters_occurrence(input_text),occurrence_correct))
