Mr. B, Mr. G and Mr. M are now in Warsaw, Poland, for the 2012’s ACM-ICPC World Finals Contest. They’ve decided to take a 5 hours training every day before the contest. Also, they plan to start training at 10:00 each day since the World Final Contest will do so. The scenery in Warsaw is so attractive that Mr. B would always like to take a walk outside for a while after breakfast. However, Mr. B have to go back before training starts, otherwise his teammates will be annoyed. Here is a problem: Mr. B does not have a watch. In order to know the exact time, he has bought a new watch in Warsaw, but all the numbers on that watch are represented in Roman Numerals. Mr. B cannot understand such kind of numbers. Can you translate for him?
输入 Each test case contains a single line indicating a Roman Numerals that to be translated. All the numbers can be found on clocks. That is, each number in the input represents an integer between 1 and 12. Roman Numerals are expressed by strings consisting of uppercase ‘I’, ‘V’ and ‘X’. See the sample input for further information. 输出 For each test case, display a single line containing a decimal number corresponding to the given Roman Numerals. 样例输入 I II III IV V VI VII VIII IX X XI XII 样例输出 Case 1: 1 Case 2: 2 Case 3: 3 Case 4: 4 Case 5: 5 Case 6: 6 Case 7: 7 Case 8: 8 Case 9: 9 Case 10: 10 Case 11: 11 Case 12: 12 import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner=new Scanner(System.in); int count=0; String arr[]={"I","II","III","IV","V","VI","VII","VIII","IX","X","XI","XII"}; while(scanner.hasNext()) { String string=scanner.nextLine(); System.out.print("Case "+(++count)+": "); for(int i=0;i<12;i++) { if(string.equals(arr[i])) { System.out.println(i+1); break; } } } } }
