数组求和题目:实现一个函数,接收一个整数数组作为参数,计算并返回数组中所有元素的和。```pythondef array_sum(arr):if len(arr) == 1:return arr[0]return arr[0] + array_sum(arr[1:])```解析:数组求和的过程可以通过递归的方式,将数组分成第一个元素和剩余部分,不断将问
A. np.array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]):这会创建一个包含指定的10个整数的NumPy数组。 B. np.arange(10):这将创建一个从0到9的整数数组,不包括10。 C. np.linspace(0, 9, 10):这会在0到9之间生成10个均匀分布的数值,包括0和9。 D. np.zeros(10):这会创建一个包含10...
