Sightseeing Trip 10 Jun 2011 16:23 first...you must know that there is only one test case, ans this test case contents lots of tests... second...if you used the floyed to calculate the minimum circle，you must check the path you recorded.and, yes, the order of the crossing is not important. ok,I WA on the recording of the path,because I ignored that floyed will change the mid node of my path... sorry for my english... there is one test case that may help you : 98 146 1 2 1 2 3 300 3 4 1 4 5 300 5 6 1 6 7 300 7 8 1 8 9 300 9 10 1 10 11 300 11 12 1 12 13 300 13 14 1 14 15 300 15 16 1 16 17 300 17 18 1 18 19 300 19 20 1 20 21 300 21 22 1 22 23 300 23 24 1 24 25 300 25 26 1 26 27 300 27 28 1 28 29 300 29 30 1 30 31 300 31 32 1 32 33 300 33 34 1 34 35 300 35 36 1 36 37 300 37 38 1 38 39 300 39 40 1 40 41 300 41 42 1 42 43 300 43 44 1 44 45 300 45 46 1 46 47 300 47 48 1 48 49 300 50 51 300 51 52 1 52 53 300 53 54 1 54 55 300 55 56 1 56 57 300 57 58 1 58 59 300 59 60 1 60 61 300 61 62 1 62 63 300 63 64 1 64 65 300 65 66 1 66 67 300 67 68 1 68 69 300 69 70 1 70 71 300 71 72 1 72 73 300 73 74 1 74 75 300 75 76 1 76 77 300 77 78 1 78 79 300 79 80 1 80 81 300 81 82 1 82 83 300 83 84 1 84 85 300 85 86 1 86 87 300 87 88 1 88 89 300 89 90 1 90 91 300 91 92 1 92 93 300 93 94 1 94 95 300 95 96 1 96 97 300 97 98 1 1 50 5 2 51 5 3 52 5 4 53 5 5 54 5 6 55 5 7 56 5 8 57 5 9 58 5 10 59 5 11 60 5 12 61 5 13 62 5 14 63 5 15 64 5 16 65 5 17 66 5 18 67 5 19 68 5 20 69 5 21 70 5 22 71 5 23 72 5 24 73 5 25 74 5 26 75 5 27 76 5 28 77 5 29 78 5 30 79 5 31 80 5 32 81 5 33 82 5 34 83 5 35 84 5 36 85 5 37 86 5 38 87 5 39 88 5 40 89 5 41 90 5 42 91 5 43 92 5 44 93 5 45 94 5 46 95 5 47 96 5 48 97 5 49 98 5 50 49 3 the answer is 49 50 1 2 51 52 3 4 53 54 5 6 55 56 7 8 57 58 9 10 59 60 11 12 61 62 13 14 63 64 15 16 65 66 17 18 67 68 19 20 69 70 21 22 71 72 23 24 73 74 25 26 75 76 27 28 77 78 29 30 79 80 31 32 81 82 33 34 83 84 35 36 85 86 37 38 87 88 39 40 89 90 41 42 91 92 43 44 93 94 45 46 95 96 47 48 97 98 Power_OJ4 Re: if you get WA at test 1 , maybe this can help you [1] // Problem 1004.

Sorry for my poor english too. :） Power_OJ4 Re: if you get WA at test 1 , maybe this can help you // Problem 1004. Sightseeing Trip 2 Aug 2011 08:20 Oh,I get AC! Beacuse my inf is too large. It should be small than INT_MAX/3. So somebody else who get WA should notice it.

Zhihua Lai Re: My AC on C# // Problem 1026. Questions and Answers 30 Nov 2011 03:21 well.... C# helps a lot. but i really think figure out yourself is better. PS: no sort is required actually. Vitaly Grebennik Re: My AC on C# // Problem 1026. Questions and Answers 29 Nov 2019 18:29 If you know the length of array it is better to create array, not to use List<>. Array is faster :) In this case you needn`t a lot of economy of time, but in some cases this can be critical.
