如何交换两个数组的成员，使两个数组元素之和的差值最小？

def swap_array_elements(arrA, arrB):
    sumA = sum(arrA)
    sumB = sum(arrB)
    diff = sumA - sumB

    if diff == 0:
        return arrA, arrB

    if diff > 0:
        for i in range(len(arrA)):
            for j in range(len(arrB)):
                if arrA[i] - arrB[j] == diff/2:
                    arrA[i], arrB[j] = arrB[j], arrA[i]
                    return arrA, arrB

    if diff < 0:
        for i in range(len(arrA)):
            for j in range(len(arrB)):
                if arrB[j] - arrA[i] == abs(diff)/2:
                    arrA[i], arrB[j] = arrB[j], arrA[i]
                    return arrA, arrB

    return arrA, arrB

# 示例用法
arrA = [1, 2, 3, 4, 5]
arrB = [6, 7, 8, 9, 10]
arrA, arrB = swap_array_elements(arrA, arrB)
print("交换后的数组A:", arrA)
print("交换后的数组B:", arrB)
