The last test case looks fine to me?
Note that Farmer John has a very large herd of cows, so although some of them are noted in his log book as changing their milk production, there are always plenty of other cows around whose milk output level remains at G gallons.

In the code y'all have initially set the total number of cows that produce the initial g milk to be N. but N is not the number of cows in the problem, N is given as the number of entries in the log!
So because the last test case involves only 1 cow being updated 2 times, the wall never changes. The answer is supposed to be 0. but it's given as 1.
If you submit the same code to the bronze problem, except setting g initially to be 7 and change the variable type of the id from int to string, you will get the first test case wrong. But if you do it my way, which is setting the total number of cows to be the number of ids scanned by all the log entries, you literally get all test cases right for the bronze problem.
