wormhole | An example for writing Golang backend web application | Runtime Evironment library

I want to display the youtube thumbnails list as a banner list in my app in Page view. I parsed the Json data using a video on youtube but I am getting an exception "Unhandled Exception: type 'double' is not a subtype of type 'int'"

I shall put down everything I have done and put a small explanation

Im new to coding, and pretty confused by the concept of class 's and how to use them. Im making a zork game as a practice exercise and have the following as part of my code:

I am new to react hooks and fairly new to react. I am trying to generate a dropdown list that pulls values from my server. I am having trouble removing the duplicates from the list. This code probably needs a lot of re working but any help would be appreciated. I include the songform.js below and I will add what my mongodb information looks like.

Stuying Springboot, I got myself into an infinite wormhole of errors. Here is the last one: No qualifying bean of type 'ca.company.hello.A' available

However, what puzzles me is that I do define the bean:

From pip install --help:

I am trying to use instances of an abstract class as a property in one of my extended QQuickItems. I have a basic class, like this:

I have installed tinymce in my EmberJS application. When I run npm start or even npm run build, I get an error like so:

I am learning QT and QT Creator to have experience in working with it. Using Arch Linux with the latest QT libraries.

On a button click function, I am trying to do the following:

The year is 2102 and today is the day of ZCO. This year there are N contests and the starting and ending times of each contest is known to you. You have to participate in exactly one of these contests. Different contests may overlap. The duration of different contests might be different.

There is only one examination centre. There is a wormhole V that transports you from your house to the examination centre and another wormhole W that transports you from the examination centre back to your house. Obviously, transportation through a wormhole does not take any time; it is instantaneous. But the wormholes can be used at only certain fixed times, and these are known to you.

So, you use a V wormhole to reach the exam centre, possibly wait for some time before the next contest begins, take part in the contest, possibly wait for some more time and then use a W wormhole to return back home. If you leave through a V wormhole at time t1 and come back through a W wormhole at time t2, then the total time you have spent is (t2 - t1 + 1). Your aim is to spend as little time as possible overall while ensuring that you take part in one of the contests.

You can reach the centre exactly at the starting time of the contest, if possible. And you can leave the examination centre the very second the contest ends, if possible. You can assume that you will always be able to attend at least one contest–that is, there will always be a contest such that there is a V wormhole before it and a W wormhole after it.

For instance, suppose there are 3 contests with (start,end) times (15,21), (5,10), and (7,25), respectively. Suppose the V wormhole is available at times 4, 14, 25, 2 and the W wormhole is available at times 13 and 21. In this case, you can leave by the V wormhole at time 14, take part in the contest from time 15 to 21, and then use the W wormhole at time 21 to get back home. Therefore the time you have spent is (21 - 14 + 1) = 8. You can check that you cannot do better than this.

The first line contains 3 space separated integers N, X, and Y, where N is the number of contests, X is the number of time instances when wormhole V can be used and Y is the number of time instances when wormhole W can be used. The next N lines describe each contest. Each of these N lines contains two space separated integers S and E, where S is the starting time of the particular contest and E is the ending time of that contest, with S < E. The next line contains X space separated integers which are the time instances when the wormhole V can be used. The next line contains Y space separated integers which are the time instances when the wormhole W can be used.

Print a single line that contains a single integer, the minimum time needed to be spent to take part in a contest.
