这道题有坑,实际上是(m+1)天,给的测试数据比测试结果少一天,加上按(m+1)天计算即可,估计出题的人自己代码写错了...
AC代码:
1 import java.util.Scanner; 2 3 public class Main { 4 5 public static void main(String[] args) { 6 7 Scanner sc=new Scanner(System.in); 8 9 int times=sc.nextInt(); 10 11 while(times-->0){ 12 int n=sc.nextInt(); 13 System.out.println(solve(n)); 14 } 15 16 } 17 18 public static int solve(int n){ 19 int ans=1; 20 while(n-->0) ans=(ans+1)*2; 21 return ans; 22 } 23 24 }
