同一个代码！这个运行时间正好是在超时的边界！~
import java.util.Scanner; public class Main { static Scanner sc=new Scanner(System.in); public static void main(String[] args) { int n=sc.nextInt(); while(n-->0){ int m=sc.nextInt(); double[] a=new double[m]; double max=a[0]=sc.nextDouble(); for(int i=1;i<a.length;i++){ a[i]=sc.nextDouble(); if(max<a[i]){ max=a[i]; } } System.out.printf("%.2f",max); System.out.println(); } } }
