Write a function build_csv_string(data) that takes in a list data. data will be a list of lists, where each sub list is of length 1, 2, or 3. Length 1 lists will contain a name (as a string). Length 2 lists will contain a name and an assignment title (as a string). Length 3 lists will contain a name, an assignment title, and a score (as a float or int). The function should return a valid csv string where each sublist is a record in the string. The header (first line) of the csv file should be 'name, assignment, grade\n'. Lists missing a grade value should use as the default, and missing assignment titles should be defaulted to 'N/A'
