Input format: - The first line contains an integer N (1 ≤ N ≤ 30). - The second line contains N integers representing daily visit change records. - The third line contains two integers A and B (1 ≤ A ≤ B ≤ N). Output format: - An integer representing the total number of visits between day A and day B. Example: Input: 7 100 200 -50 300 -100 150 100 3 5 Output: 350
