There are many tasks in leetcode which have inputs as INT_MAX or INT_MIN.
In some task it is alright to have them as input as they might be edge case (overflowing is not edge case it is just stupid to have them as test for overflow cause in interview we deal with logic not with overflows).
But there are many tasks where the input as INT_MAX or INT_MIN are not required at all. Rather they annoy, as a general solution to them is to change int to long or long long.
I guess people were so occupied in getting leetcode coins that they didn't even think about they are not contributing some edge case, rather they are just contributing some boundary values for easy leetcode coins.
