Are there troubles with ll-values in test cases for NailingABanner and BannerWithNails? With NailingABanner: test case 2 with input 3 should return 576460752303423488. If solution returns it, it is displayed as "Return value: 576460752303423500" in the test report, but evaluated correctly as "correct". Ok, it may be not so annoying, but in BannerWithNails it is an inverted situation. Solution should get 576460752303423488 as input, but gets 576460752303423500, evaluated as N/A. Test case 4 should have maximal possible input 2^60, but solution gets 1152921504606847000 == 2^60 + 24, what is resulting in test error "X must be between 0 and 2^60, inclusive". Looks like ll-values being casted to single and back.

Is it only now in practice room or has it already been so during the tournament? Should one know this "feature"?
