哈哈哈哈, 又用Java强大的字符串API和集合类水过一道题,不服用C++来一遍看看比这个代码长多少(不考虑时间的情况下)。
import java.util.*; public class Main1584 { public static void main(String[] args) { Scanner scan = new Scanner(System.in); ArrayList<String> arrlist = new ArrayList<String>(); String s; int n; n = scan.nextInt(); while(n-- > 0) { arrlist.clear(); s = scan.next(); arrlist.add(s); for(int i=1; i<s.length(); i++) { StringBuilder strB = new StringBuilder(); strB.append(s.substring(i)); strB.append(s.substring(0, i)); arrlist.add(strB.toString()); } Collections.sort(arrlist); System.out.println(arrlist.get(0)); } } }
