我用了一个On数组 也是 爆内存

Scanner scanner = new Scanner(System.in); int n=scanner.nextInt(); int []array=new int[n]; if(n%2==0) { for (int i = 0; i < n; i++) { if (i % 2 == 1) {
             array[n / 2 - (i + 1) / 2] = scanner.nextInt();
         } else {
             array[i / 2 + n / 2] = scanner.nextInt();
         }
     }
 }else{ for(int i=0;i<n;i++){ if(i%2==0){
             array[(n-1)/2-i/2]=scanner.nextInt();
         }else{
             array[(i+1)/2+(n-1)/2]=scanner.nextInt();
         }
     }
 } for(int i=0;i<n;i++){ if(i==n-1){
         System.out.print(array[i]);
     }else System.out.print(array[i]+" ");

 }
