The task is to append a swarm of small circles around the nodes of a tree (where I have placed bigger circles). The depth of the tree is tiny -- just two, However, there is a slight degree of complexity when considering I'm appending several trees iteratively.

To keep it simple, I didn't even try to append swarms to all trees. Instead, I set myself with a more modest goal of appending the swarm to just one node of one tree. Comments and snippet below:

Lets suppose i have two strings string1 and string2.

var string1 = "images of canadian geese goslings";

var string2 = "Canadian geese with goslings pictures to choose from, with no signup needed";

I need to find biggest substring of string1 which matches in string2.

here biggest substring will be "canadian geese" which is matching in string2.

How can I find it? I tried breaking string1 into char[] and find words then merged matched words but that failed my objective.

So I have nested div tags in the HTML file. I was trying to copy certain texts from each div tag. After searching for several hours finally I found the solution which worked. The solution below:

I am trying to use the below data to get the 'Total Facebook likes' for each unique actor. The output should be in two columns, column 1 containing the unique actor names from all the actor_name columns and column 2 should have the total likes from all three actor_facebook_likes columns. Any idea on how this can done, will be appreciated.

I'm coming from a Java background, and I'm trying to wrap my head around Haskell's type system. In the Java world, the Liskov Substitution Principle is one of the fundamental rules, and I'm trying to understand if (and if so, how) this is a concept that applies to Haskell as well (please excuse my limited understanding of Haskell, I hope this question even makes sense).

For example, in Java, the common base class Object defines the method boolean equals(Object obj) which is consequently inherited by all Java classes and allows for comparisons like the following:

I am creating a GIF search web app with the GIPHY API and react.

After I fetch the data from the API, I can index the data console.log(json.data[0])

I successfully got the Spotify API to work with spotify-web-api-js, but I have no idea how to decode this. I want to be able display the title and artist of the song currently playing on a HTML page.

Right now to test, I'm trying to use (data is the stuff from the Spotify api) to get the timestamp since I don't know what the format is to go deeper into the Spotify response. I get an Uncaught TypeError: Cannot read property 'timestamp' of undefined.

Note: I'm new to coding

Here's the javascript that gets the stuff from Spotify:

I have multiple jsons coming from any restapi's and I don't know the schema of it. I am unable to use the explode function of dataframes , because i am unaware about the column names, which is getting created by spark api.

1.Can we store the keys of the nested arrays elements keys by decoding values from dataframe.schema.fields, As spark only provides the value part in the rows of the dataframe and take the top level key as column name.

In this React component, I'm trying to fetch data from the GIPHY API and render it in another component. The fetch is working correctly, but this.state.gifs.map returns an error because it runs before the fetch is complete and the state is set. I have tried using Hooks with async/await but that did not seem to work either. How can I create my gifArray after the state is set so I'm not trying to run .map on an empty array.
