array = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) row_sums = np.sum(array, axis=0) col_sums = np.sum(array, axis=1) print(row_sums) # 输出结果为[12 15 18] print(col_sums) # 输出结果为[ 6 15 24] 综上所述,sum在编程中通常指的是求和操作。它可以用于计算一组...
编写一个Java程序,实现计算数组中所有元素的和。 ```java public class ArraySum { public static void main(String[] args) { int[] numbers = {1, 2, 3, 4, 5}; int sum = 0; for (int number : numbers) { sum += number; } System.out.println("Sum of array elements is: " + sum)...
leetcode上167号问题:Two Sum II 给定一个已按照升序排列 的有序数组,找到两个数使得它们相加之和等于目标数。 函数应该返回这两个下标值 index1 和 index2,其中 index1 必须小于 index2。 说明: 返回的下标值(index1 和 index2)不是从零开始的。 你可以假设每个输入只对应唯一的答案,而且你不可以重复使用...
