不明白测试提交不给通过，觉得思路是正确的？？？？？？？？？

public class Main {
  
    public  void  getMax() {
        int n;
        Scanner in=new Scanner(System.in);
        n=in.nextInt();
        int[] corn=new int[n];
        int[] left=new int[n+1];
        int[] right=new int[n+1];
        
        for(int i=0;i<n+1;i++) {
            left[i]=in.nextInt();
            right[i]=in.nextInt();
        }
        
        for(int i=1;i<n+1;i++) {
            for(int j=i+1;j<n+1;j++) {
                int mul1=left[i]*right[i];
                int mul2=left[j]*right[j];
                if(mul1>mul2){
                    swap(left,i,j);
                    swap(right,i,j);
                }
            }
        }
