代码实现

package com.atguigu.TEST;import java.util.Arrays;
import java.util.Collections;
import java.util.Scanner;class Main{public static long  arr[][]=new long[30][30];public static void main(String[] args) {Scanner scanner = new Scanner(System.in);long factor=1;for (int i = 0; i < 30; i++) {factor<<=1;}System.out.println(factor);//输入数据放入二维数组for (int i = 0; i < 29; i++) {for (int j = 0; j <= i; j++) {arr[i][j]=scanner.nextInt()*factor;}}scanner.close();//自上而下处理a[i][j]*factor(2的30次方)-->除以2,计入a[i+1][j]和a[i+1][j+1]for (int i = 0; i < 29; i++) {for (int j = 0; j <= i; j++) {long ha = arr[i][j] / 2;arr[i+1][j]+=ha;arr[i+1][j+1]+=ha;}}Arrays.sort(arr[29]);System.out.println(arr[29][0]/2);System.out.println(arr[29][29]/2);}
