🏆 InterSystems Grand Prix Programming Contest 🏆

In prizes: more than $22,000

Contest running: May 9 - 29, 2022

Voting period: May 30 - June 5, 2022

We need to send some coordinates to a spaceship through a laser beam. To do that we have to encode it, and beam it out into space. Your mission is to implement the encoder with a compression standard. As usual shortest solution wins.

Task

You will receive a string of comma-separated integers and you will return a new string of comma-separated integers and sequence descriptors.

Input

"0,2,4,5,5,5,5,5,3,4,5"

Output

"0-4/2,5*5,3-5"

Note

• Compression happens left to right
• A sequence of 2 or more identical numbers is shortened as number*count
  • example: "5,5,5" is compressed to "5*3"
• A sequence of 3 or more consecutive numbers is shortened as first-last. This is true for both ascending and descending order
  • example: "1,3,4,5" is compressed to "1,3-5"
• A sequence of 3 or more numbers with the same interval is shortened as first-last/interval.
  • example: "0,2,4,6" is compressed to "0-6/2"
• Use this code to check the result length
• You also can use this test case here

Rules

1. The signature of the contest entry MUST be:

Class dc.golf.Encoder {

ClassMethod Compress(a)
{
}

}

2. It is forbidden to modify class/signature, including but not limited to:

• Adding inheritance
• Setting default argument values
• Adding class elements (Parameters, Methods, Includes, etc).

3. It is forbidden to refer to non-system code from your entry. For example, this is not a valid entry:

ClassMethod Compress(a)
{
  q ##class(myPackage.myClass).test(a)
}

4. The use of $ZWPACK and $ZWBPACK is also discouraged.

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the word anagram itself can be rearranged into nag a ram, also the word binary into brainy and the word adobe into abode. Wikipedia

You will receive two strings returning true if the two arguments given are anagrams of each other. As usual shortest solution wins.

##Input "Listen", "Silent"

##Output 1

##Note

• Both arguments are case insensitive, only a-z, A-Z, no special characters except whitespace
• The arguments could contain whitespace
• Use this code to check the result length
• You can also use this test case here

Rules

1. The signature of the contest entry MUST be:

Class codeGolf.Anagram
{

ClassMethod Detector(a As %String, b As %String) As %Boolean
{
  ; your code here
}

}

2. It is forbidden to modify class/signature, including but not limited to:

• Adding inheritance
• Setting default argument values
• Adding class elements (Parameters, Methods, Includes, etc).

3. It is forbidden to refer to non-system code from your entry. For example, this is not a valid entry:

ClassMethod Detector(a As %String, b As %String) As %Boolean
{
  q ##class(myPackage.myClass).test(a)
}

4. The use of $ZWPACK and $ZWBPACK is also discouraged.

Hey community! How are you doing?

I hope to find everyone well, and a happy 2022 to all of you!

Over the years, I've been working on a lot of different projects, and I've been able to find a lot of interesting data.

But, most of the time, the dataset that I used to work with was the customer data. When I started to join the contest in the past couple of years, I began to look for specific web datasets.

I've curated a few data by myself, but I was thinking, "This dataset is enough to help others?"

So, discussing the ideas for this contest with @José Pereira , we decided to approach this contest using a different perspective.

We thought of offering a variety of datasets of any kind from two famous data sources. This way, we can be empowering the users to find and install the desired dataset in a quick and easy way.

Socrata

The Socrata Open Data API allows you to programmatically access a wealth of open data resources from governments, non-profits, and NGOs around the world.

For this initial release, we are using Socrata APIs to search and download and speficic dataset.

Open the API tool of your preference like Postman, Hoppscotch

GET> https://api.us.socrata.com/api/catalog/v1?only=dataset&q=healthcare

This endpoint will return all healthcare related datasets, like the image below:

Now, get the ID. In this case the id is: "n9tp-i3k3"

Go the the terminal

IRISAPP>set api = ##class(dc.dataset.importer.service.socrata.SocrataApi).%New()

IRISAPP>do api.InstallDataset({"datasetId": "n9tp-i3k3", "verbose":true})

Compilation started on 01/07/2022 01:01:28 with qualifiers 'cuk'
Compiling class dc.dataset.imported.DsCommunityHealthcareCenters
Compiling table dc_dataset_imported.DsCommunityHealthcareCenters
Compiling routine dc.dataset.imported.DsCommunityHealthcareCenters.1
Compilation finished successfully in 0.108s.

Class name: dc.dataset.imported.DsCommunityHealthcareCenters
Header: Name VARCHAR(250),Description VARCHAR(250),Location VARCHAR(250),Phone_Number VARCHAR(250),geom VARCHAR(250)
Records imported: 26

After the command above, your dataset it's ready to use!

Kaggle

Kaggle, a subsidiary of Google LLC, is an online community of data scientists and machine learning practitioners. Kaggle allows users to find and publish data sets, explore and build models in a web-based data-science environment, work with other data scientists and machine learning engineers, and enter competitions to solve data science challenges.

In June 2017, Kaggle announced that it passed 1 million registered users, or Kagglers, and as of 2021 has over 8 million registered users. The community spans 194 countries. It is a diverse community, ranging from those just starting out to many of the world's best known researchers.

This what I call a huge community, right?!

To use the datasets from Kaggle, you need to register on the website. After that, you need to create an API token to use Kaggle's API.

Now, just like with Socrata, you can use the API to search and download the dataset.

GET> https://www.kaggle.com/api/v1/datasets/list?search=appointments

Now, get the ref value. In this case the ref is: "joniarroba/noshowappointments"

The parameters below "your-username", and "your-password" are the parameters provided by Kaggle when you create the API token.

IRISAPP>Set crendtials = ##class(dc.dataset.importer.service.CredentialsService).%New()

IRISAPP>Do crendtials.SaveCredentials("kaggle", "<your-username>", "<your-password>")

IRISAPP>Set api = ##class(dc.dataset.importer.service.kaggle.KaggleApi).%New()

IRISAPP>Do api.InstallDataset({"datasetId":"joniarroba/noshowappointments", "credentials":"kaggle", "verbose":true})

Class name: dc.dataset.imported.DsNoshowappointments
Header: PatientId INTEGER,AppointmentID INTEGER,Gender VARCHAR(250),ScheduledDay DATE,AppointmentDay DATE,Age INTEGER,Neighbourhood VARCHAR(250),Scholarship INTEGER,Hipertension INTEGER,Diabetes INTEGER,Alcoholism INTEGER,Handcap INTEGER,SMS_received INTEGER,No-show VARCHAR(250)
Records imported: 259

After the command above, your dataset it's ready to use!

Graphic User Interface

We're offering a GUI to install the dataset to make things easier. But this is something that we like to discuss in our next article. In the meanwhile, you can check a sneak peek below while we are polishing a few things before the official release:

Video Demo

How is the behavior of downloading a bigger dataset? +400.000 records aren't enough?! How about 1 MILLION RECORDS?! Let's see it!

Here are the projects that scored it:

Hi everyone,

I want to talk about our project and use the dataset theme for this contest.

Our intention never was to be a data curator, especially because sometimes my precious data means a lot for me, but not for the rest of the world.

We want to go a step further and empower the user to find the perfect dataset for their needs.

Our project is a bridge between the data science community and the developer's community using InterSystems IRIS to achieve this mission.

The image below it's the initial page for you. You can search for any topic, and you can see the datasets that are related to it.

Just click on the magnifying glass icon next to Socrates mascot, the search bar will appear and you can start searching for any topic.

But remember, the search value is required, so you can't search for "nothing". If you try to search for an empty string, will be notified like the alert image below:

Searching for a specific topic, will fill the datatable with the datasets that are related to it.

Here it's a demo video showing how you choose a dataset, look for the details, download and install it.

Hi all,
I try to build a little project for the dataset contest, you can find it here on github: Openflights dataset
My plan is to use just plain SQL. So I've made a few experiments with the new feature LOAD DATA.

Unfortunately all loads produce errors like:  
 Error: [SQLCODE: <-400>:<Fatal error occurred>]
[Error: <<UNDEFINED>zExecute+83^%sqlcq.OPENFLIGHTS.cls4.1 *%qparsets>]
[Location: <ServerLoop>]

The statements I use looks like this:

Hi developers!

We launched the datasets contest.

And one of the important questions that need to be covered is dataset licensing.

There are two general cases:

a) a dataset you take from another place in public Internet or private network/person.

b) a dataset you create by yourself or own for any other reason.

We decided to follow the principles and considerations that data.world site introduces for datasets' licensing.
