求和、减法和乘法数组

# 求和
def array_sum(arr):
    return sum(arr)

# 减法
def array_subtract(arr1, arr2):
    return [a - b for a, b in zip(arr1, arr2)]

# 乘法
def array_multiply(arr):
    result = 1
    for num in arr:
        result *= num
    return result

# 示例数组
arr1 = [1, 2, 3, 4]
arr2 = [5, 6, 7, 8]

# 执行操作
print("Sum:", array_sum(arr1))  # 输出求和结果
print("Subtract:", array_subtract(arr1, arr2))  # 输出减法结果
print("Multiply:", array_multiply(arr1))  # 输出乘法结果

def array_subtract(arr1, arr2):
    if len(arr1) != len(arr2):
        raise ValueError("Arrays must be of the same length")
    return [a - b for a, b in zip(arr1, arr2)]

def array_multiply(arr):
    if 0 in arr:
        return 0
    result = 1
    for num in arr:
        result *= num
    return result
