参考代码:
import java.util.Scanner; public class Main{ public static void main(String[] args) { Scanner sc = new Scanner(System.in); int a = sc.nextInt(); for (int b = 0; b < a; b++) { int n = sc.nextInt(); int[][] dp = new int[n][n]; for (int i = 0; i < n; i++) { for (int j = 0; j <= i; j++) { dp[i][j] = sc.nextInt(); } } for (int i = n-2; i >= 0 ; i--) { for (int j = 0; j <= i; j++) { dp[i][j] += Math.max(dp[i+1][j],dp[i+1][j+1]); } } System.out.println(dp[0][0]); } } }
