从一个数组到另一个数组中获取数字，而不是从另一个数组中获取数字

def find_common_numbers(array1, array2):
    result = []
    for num in array1:
        if num in array2:
            result.append(num)
    return result

# 使用示例
array1 = [1, 2, 3, 4, 5]
array2 = [3, 4, 5, 6, 7]
common_numbers = find_common_numbers(array1, array2)
print(common_numbers)

def find_unique_numbers(array1, array2):
    result = []
    for num in array1:
        if num not in array2:
            result.append(num)
    return result

# 使用示例
array1 = [1, 2, 3, 4, 5]
array2 = [3, 4, 5, 6, 7]
unique_numbers = find_unique_numbers(array1, array2)
print(unique_numbers)
