今天看《高並發》書,寫了一個多線程的類,發現測試方法輸出的結果並不對;同樣的代碼,經過main方法後輸出的結果卻是正常的;經過研究後發現單元測試@Test並不支援多線程測試;以下為分析過程: private static ExecutorService ex = Executors.newFixedThreadPool(5); public static class myTask implements Runnable{ @Override public
Given an array of integers, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Please note
Majority Element Total Accepted: 44517 Total Submissions: 127008 My Submissions Question Solution Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that
public class Solution { class KeyPoint { public int key; public int height; public KeyPoint next = null; public KeyPoint(int key, int height) { this.key = key; this.height = height; } }
Given an array containing n distinct numbers taken from 0, 1, 2, …, n, find the one that is missing from the array. For example, Given nums = [0, 1, 3] return 2. Note: Your algorithm should run in linear runtime complexity. Could you implement
Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating letters for “abcabcbb” is “abc”, which the length is 3. For “bbbbb” the longest substring is “b”, with the
