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)...
Given an array A of integers, we must modify the array in the following way: we choose an i and replace A[i] with -A[i], and we repeat this process K times in total. (We may choose the same index i multiple times.) Return the largest possible sum of the array after modifying i...

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相同的元素。
importjava.util.Scanner; publicclassSum_Odd_Even { publicstaticvoidmain(String[]args) { intn, sumE=0, sumO=0; Scanner s=newScanner(System.in); System.out.print("Enter the number of elements in array:"); n=s.nextInt(); int[]a=newint[n]; ...
Given an integer arraynumsand an integerk, modify the array in the following way: choose an indexiand replacenums[i]with-nums[i]. You should apply this process exactlyktimes. You may choose the same indeximultiple times. Returnthe largest possible sum of the array after modifying it in th...
This function executes for each element in the array. It returns a single value, in this case will be sum of the numbers of the array.Syntax:array.reduce(function(total, currentValue, currentIndex, arr), initialValue) The terms defined inside the bracket are the parameters that reduce() ...
Since version 2.4, Ruby has provided a concise and elegant solution for summing an array of numbers: theArray#summethod. This method simplifies the process of calculating the sum of elements in an array. The syntax for using theArray#summethod is quite straightforward: ...
