最大子序列和是一道经典的算法题, leetcode 也有原题《53.maximum-sum-subarray》,今天我们就来彻底攻克它。 题目描述 求取数组中最大连续子序列和,例如给定数组为 A = [1, 3, -2, 4, -5], 则最大连续子序列和为 6,即 1 + 3 +(-2)+ 4 = 6。去 首先我们来明确一下题意。 题目说的子数组...
public class Sum { public static void main(String[] args){ String str[]={"12","13","25"}; int sum1=0; for(int i=0;i<str.length;i++){ int myint=Integer.parseInt(str[i]); sum1=sum1+myint; } System.out.println("数组中的各元素之和是:"+sum1); } } 结果显示: 数组中...
This example program leverages an executor to compute sums of long integers. The inner Sum class implements the Callable interface that is used by executors for result-bearing computations, and the concurrent work is performed within the call() method. The java.util.concurrent.Executors class provid...
这里有很多知识点值得说。首先,tasks集合被转换成steam表示;其次,在steam上的filter操作会过滤掉所有CLOSED的task;第三,mapToInt操作基于每个task实例的Task::getPoints方法将task流转换成Integer集合;最后,通过sum方法计算总和,得出最后的结果。 在学习下一个例子之前,还需要记住一些steams(点此更多细节)的知识点。Ste...
