Minimum Set Difference

You are given two arrays of integers. Your task is to find the minimum difference between any element of the first array and any element of the second array. Input Format: - The first line contains an integer n (1 <= n <= 1000), the number of elements in the first array. - The second line contains n integers representing the elements of the first array. - The third line contains an integer m (1 <= m <= 1000), the number of elements in the second array. - The fourth line contains m integers representing the elements of the second array. Output Format: - Output a single integer representing the minimum difference. Example Input: 3 1 5 9 4 10 1 7 4 Example Output: 1
