  2. hi binghan, can you please tell me whether test case 1 output (50091 49909) is right?
    I checked on my solution and its giving 50089 49911.. but takes more than 10 minutes to run on such a big data..
    is it acceptable?

  3. Hi sol0, the output should be correct. 10 minutes is too long, you might want to optimize your algorithm to fit into less than 5 seconds.


    You can follow the discussion here http://on.fb.me/imA0zv. You will most people got it around 2 second.
