Answer 2

Insecurities research, an analyst will look data the number of attributes for a stock.

One analyst would like to keep a record of the highest positive spread between a closing price and the closing price on any prior day in history.

Explanation:

static int maxDifference(int[] a) {

   //test array size

   if (a.length < 1 || a.length > 1_000_000) return -1;

   int[] oldArr = Arrays.copyOf(a, a.length);

   Arrays.sort(a);

   int max = a[a.length - 1];

   if (max > 1_000_000 || a[0] < -1_000_000) return -1;

   int min = max;

   for (int i = 0; i < oldArr.length; i++) {

       if (oldArr[i] < max) {

           min = Math.min(min, oldArr[i]);

       }

       if (oldArr[i] == max) break;

   }

   int result = min == max ? -1 : max - min;

   return result;

}
