Topic Array Two Pointers Description https://leetcode.com/problems/3sum-closest/ Given an array nums of n integers and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution. Example 1 : Input: nums = [-1,2,1,-4], target = 1 Output: 2 Explanation: The sum that is closest to the target is 2. (-1 + 2 + 1 = 2). Constraints : 3 <= nums.length <= 10³ -10³ <= nums[i] <= 10³ -10⁴ <= target <= 10⁴ Analysis 方法一：我写的，受到 LeetCode - Medium - 15. 3Sum 启发而写，幸运成功地成功验收。与方法二相比

问题 I have a JUnit test that starts an spring-boot application (in my case, the main class is SpringTestDemoApp ) after the test: @WebIntegrationTest @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = SpringTestDemoApp.class) public class SpringTest { @Test public void test() { // Test http://localhost:8080/ (with Selenium) } } Everything works fine using spring-boot 1.3.3.RELEASE . Nevertheless, the annotation @WebIntegrationTest and @SpringApplicationConfiguration

RestAssuredMockMvc Connection to http://localhost:8080 refused

问题 I developed a Spring MVC webapp with rest methods. I would love to use RestAssured to create JUnit test classes. From the documentation it looks really simple to do but I'm having some problem instead. Basically I want to use it to avoid a runtime Tomcat instance but the problem is that when I execute the JUnit test class I obtain the following exception: org.apache.http.conn.HttpHostConnectException: Connection to http://localhost:8082 refused ... Caused by: java.net.ConnectException:

Topic String Dynamic Programming Description https://leetcode.com/problems/longest-palindromic-substring/ Given a string s , return the longest palindromic substring in s . Example 1 : Input: s = "babad" Output: "bab" Note: "aba" is also a valid answer. Example 2 : Input: s = "cbbd" Output: "bb" Example 3 : Input: s = "a" Output: "a" Example 4 : Input: s = "ac" Output: "a" Constraints : 1 <= s.length <= 1000 s consist of only digits and English letters (lower-case and/or upper-case), Analysis 方法一：以字符为中心向其两侧扩展探测是否回文。 方法二：动态规划。 dp(i, j) represents whether s(i ... j) can form a palindromic

Why isn't JUnit TemporaryFolder deleted?

问题 The documentation for JUnit's TemporaryFolder rule states that it creates files and folders that are "guaranteed to be deleted when the test method finishes (whether it passes or fails)" However, asserting that the TemporaryFolder does not exist fails: import static org.junit.Assert.*; import org.junit.After; import org.junit.Before; import org.junit.Rule; import org.junit.Test; import org.junit.rules.TemporaryFolder; public class MyTest { @Rule public TemporaryFolder _tempFolder = new
