Most likely due to the test validator not being correct. The test that was used to hack shouldn't exist. If you look at the generator and the test that hacked tourist or other people, there are 999 test cases and in every test case n = 100, m = 100. But this isn't possible because it was guaranteed that sum of n * m over every test case <= 200000.
