Language: Distant Galaxy
Description You are observing a distant galaxy using a telescope above the Astronomy Tower, and you think that a rectangle drawn in that galaxy whose edges are parallel to coordinate axes and contain maximum star systems on its edges has a great deal to do with the mysteries of universe. However you do not have the laptop with you, thus you have written the coordinates of all star systems down on a piece of paper and decide to work out the result later. Can you finish this task? ![]() Input There are multiple test cases in the input file. Each test case starts with one integer N, (1 ≤ N ≤ 100), the number of star systems on the telescope. N lines follow, each line consists of two integers: the X and Y coordinates of the Kth planet system. The absolute value of any coordinate is no more than 109, and you can assume that the planets are arbitrarily distributed in the universe. N = 0 indicates the end of input file and should not be processed by your program. Output For each test case, output the maximum value you have found on a single line in the format as indicated in the sample output. Sample Input 10 2 3 9 2 7 4 3 4 5 7 1 5 10 4 10 6 11 4 4 6 0 Sample Output Case 1: 7 Source |
