还要如何优化啊

换语言2333
Java速度不敢恭维

@[流风之回雪](/space/show?uid=58448) 不知道为什么我都把转换公式那航放在输入的循环里面，时间竟然不会减少```
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= i; j++) {
a[i][j]=sr.nextInt();
a[i][j]+=Math.max(a[i-1][j], a[i-1][j-1]);
}
}
```

```java
import java.util.Scanner;
public class Main {
public static void main(String args[]){
Scanner sr = new Scanner(System.in);
int n=sr.nextInt();
int a[][]=new int[n+1][n+1];
int max=0;
for (int i = 1; i <= n; i++) {
for (int j = 1; j <= i; j++) {
a[i][j]=sr.nextInt();
a[i][j]+=Math.max(a[i-1][j], a[i-1][j-1]);
}
}
for (int i = 1; i <= n/2+1; i++) {
int x=Math.max(a[n][i],a[n][n+1-i]);
if(x>max) max=x;
}
System.out.println(max);
}
}
```改成这样时间都没减少，有点假

Java实在是慢qwq
