问题 I have a flat map of type Map<String, String> from which I would like to restore the original value tree Map<String, Object> . Elements of the tree can be either Map<String, Object> , or List<Object> , or simply String . The depth of the tree is not limited. For example: public static void main(String[] args) { TreeMap<String, String> flatMap = new TreeMap<String, String>() {{ put("1999.3:1", "23"); put("1999.3:2", "24"); put("1999.3:3", "25"); put("1999.4:1", "1"); put("1999.4:2", "2"); put(

问题 I'm working with a third-party library that provides tree-based data structures that I have to use "as is". The API returns Result<T, Error> . I have to make some sequential calls and convert the error to my application's internal error. use std::error::Error; use std::fmt; pub struct Tree { branches: Vec<Tree>, } impl Tree { pub fn new(branches: Vec<Tree>) -> Self { Tree { branches } } pub fn get_branch(&self, id: usize) -> Result<&Tree, TreeError> { self.branches.get(id).ok_or(TreeError {

问题 I have 3 arrays like this: $a = array( 0 => 'a1', 1 => 'a2', 2 => 'a3' ); $b = array( 0 => 'b1', 1 => 'b2', 2 => 'b3' ); $c = array( 0 => 'c1', 1 => 'c2', 2 => 'c3' ); and I like to have something like this: $r = array( 0 => 'a1', 1 => 'b1', 2 => 'c1', 3 => 'a2', 4 => 'b2', 5 => 'c2', 6 => 'a3', .... ... ); How can I do this AND enjoy the ability to use more then 3 input arrays? EDIT: I have tried this: $a = array( 0 => 'a1', 1 => 'a2', 2 => 'a3', 3 => 'a4' ); $b = array( 0 => 'b1', 1 => 'b2'

问题 I would like to know if anyone knows how to flatten the package structures in Visual Studio Code. I used to have this in my IntelliJ IDE, but with VS Code I can't find a similar option. I am looking for any solution which could resolve this. Either changing settings or extensions if available. 回答1: This is supported since the 1.41 release (November 2019) and enabled by default. VSCode calls this feature "compact folders", and it can be disabled like this: "explorer.compactFolders": false (gif

问题 I have two different structured json files being piped in from a snowpipe. The only difference is that instead of a nested dict it has many nested arrays. I am trying to figure out how to transform structure 1 into one finalized table. I've successfully transformed structure 2 into a table and included the code below. I know I need to be making use of lateral flatten but have not been successful. **Structure 1: Nested Arrays (Need help on)** This json lives within a table and in column *
