挑战成功，代码如下：

import java.util.Scanner;

public class Children {
    
    public static void main(String[] args) {
        Scanner cin = new Scanner(System.in);
        
        int n = 0;
        int sweetCount = 0;
        while (cin.hasNext()) {
            sweetCount = 0;
            n = cin.nextInt();
            int[] ratings = new int[n];
            for (int i = 0; i < n; i++) {
                ratings[i] = cin.nextInt();
            }
            
            int[] sweets = new int[n];
            sweets[n - 1] = 1;
            for (int i = n - 1; i > 0; i--) {
                int j = i;
                if (ratings[j] < ratings[j - 1]) {
                    sweets[j - 1] = sweets[j] + 1;
                }
                else if (ratings[j] == ratings[j - 1]) {
                    sweets[j - 1] = 1;
                }
                else {
                    if (sweets[j] == 1) {
                        for (int k = j; k < n; k++) {
                            sweets[k]++;
                            if (k == n - 1 || ratings[k] >= ratings[k + 1]
                                || (ratings[k] < ratings[k + 1] && sweets[k] < sweets[k + 1]))
                                break;
                        }
                    }
                    sweets[j - 1] = 1;
                }
            }
            
            for (int i : sweets) {
                sweetCount += i;
            }
            System.out.println(sweetCount);
            
        }
        cin.close();
    }
}
