[Question][Hw2] Got some tests wrong when using Int32 library for arithmetic operations

YOUR QUESTION

I got 77/77 tests correct when I used Int to do integer arithmetic operations, while I got 76/77 tests correct when I used Int32 instead.

In my repository, master branch got all tests correct, and int32 branch got 76/77 tests correct. The difference between these branches is a single commit in the int32 branch that does operations with Int32 library.

I'm wondering if there is a test causing int32 overflow in the hidden tests. Also, given that signed integer overflow in C is undefined behavior, should I raise Invalid_argument if integer overflow happens?

Hi, you must indeed raise Invalid_argument for any undefined behaviors.
However, the specific test case you mentioned was a mistake, and we will fix it so that both of your branches can pass.

Checked that it doesn't affect the result, thanks.
