The longest common subsequence of strings s1, s2 is the longest string s such that s is a subsequence of both s1 and s2, i.e. we can get s by starting at some point in si, reading through, perhaps skipping some letters, and then stopping at some point. Suppose now our alphabet contains a special ‘anchor’ character * which binds ‘more strongly’ than ordinary letters: concretely, when reading through each si to find s we are not allowed to skip any *s (although there may be *s outside the section of si we read). So for example, suppose that s1 = A ∗ BCD∗ and s2 = B ∗ CAD. We would not be allowe ..read more

public class Main { public static void main(String[] args) { A a =null; try{ a = new A(1); }catch (IOException e) { System.out.println(a == null); } } } class A { private int v; public A(int val) throws IOException { v= val; throw new IOException("123"); } } as far as i know the process of new a object has 3 steps: 1. allocate memory 2. execute construct function 3. assign to reference due to instruction reordering, the process may be changed to 1->3->2 rather than 1->2->3. so will the result of the code above always be true? sorry for my english ..read more

Garbage collection (GC) is a fundamental aspect of memory management in Node.js applications. However, inefficient garbage collection can lead to performance issues, causing application slowdowns and potentially impacting user experience. To ensure optimal performance and diagnose memory problems, it’s essential to study garbage collection traces. In this blog post, we’ll explore various methods for capturing garbage collection traces from Node.js applications. Options to capture Garbage Collection traces from Node.js applications There are 3 options to capture Garbage Collection traces fro ..read more
