Question:

The function predictAnswer should be made based on the following.

In the prediction game, the first player gives the second player some stock market data for some consecutive days. The data contains a company's stock price on each day. The rules for the game are:

1. Player 1 will tell player 2 a day number
2. Player 2 has to find the nearest day on which stock price is smaller than the given day
3. If there are two results, then player 2 finds the day number which is smaller
4. If no such day exits, then the answer is -1.

Example 1;

stockData size n =10;

stockData = [5,6,8,4,9,10,8,3,6,4]

queries = [6,5,4]

Result is [5,4,8]

On day 6, the stock price is 10. Both 9 and 8 are lower prices one day away. Choose 9 (day 5) because it is before day 6. On day 5, the stock price is 9. 4 is the closest lower price on day 4. On day 4, the stock price is 4. The only lower price is on day 8. The return array is [5,4,8]

Example - 2

stockData size n = 10

stockData = [5,6,8,4,9,10,8,3,6,4]

queries = [3,1,8]

Result is [2,4,-1]

If the day number is 3.both days 2 and 4 are smaller.choose the earlier day,day 2.

If the day number is 1,day 4 is the closet day with a smaller price.

If the day number is 8,there is no day where the price is less than 3.

The return array is [2,4,-1]
