Sample Output 180.00 182.00
import java.util.Scanner;public class Main { public static void main(String args[]){ Scanner sc=new Scanner(System.in); int t=sc.nextInt(); while(t-->0){ int n=sc.nextInt(); double max=sc.nextDouble(); for(int j=1;j<n;j++){ double m=sc.nextDouble(); if(m>max) max=m; } System.out.printf("%.2f",max); System.out.println(); } }}新聞熱點
