A comma-delimited string of "string" questions to form a two-dimensional array

Topic:

There is a string that conforms to the following characteristics ("Abcdef,acccd,eeee,aaaa,e3eeeee,sssss,"),

Required to write a function (interface), output the following results
1) The string is separated by commas, the two-dimensional array is formed, and the result is transmitted.
2) The results of the two-dimensional array rows are also spread out.
Please define an interface (function) yourself.
Requirement 1: Can correctly express the requirements of the function, define the interface (function) (30 points);
Requirement 2: Properly implement the interface (function), and realize the function (40 points);

Requirement 3: Write the correct test case. (30 points).
