Challenge

Time for the next #JetBrainsQuest!

It ’s easy to see that this is an English sentence in reverse order. After reversing, we can see this.

The product domain-specific languages are specified, is where the next of quest hides. The case where Dutch tax is processed is a place you should show interest. Look hard as when text is white, sometimes it is out of sight. Cmd/Ctrl+A helps.

Question 2 Find the Area

I made the keywords bold, which are domain-specific languages andDutch tax. We go to the product list and it is not difficult to find that MPS is the target.

Click Learn more and find another keywordDutch tax to view the report.

According to the prompt, using Control / Command + A, you will find a blank area is different.

Copy and paste in the text box, you can see the following.

This is our 20th year as a company,
we have shared numbers in our JetBrains
Annual report, sharing the section with
18,650 numbers will progress your quest.

Keywords: 20th 、 Annual report 、 18650 、 sharing the section

Question 3 Find the Number within Report

Then you have to find the annual report of JetBrains. Generally, such reports are placed in related forums or blogs. We look for it in the upper right corner of the official website.

After entering the blog, the annual report is an article within 0 to 4 months. After looking for a few articles, you will find an article named [JetBrains 20th Birthday Round-up] (https: // blog .jetbrains.com / blog / 2020/02/18 / jetbrains-20th-birthday-round-up /), which mentions the annual report [JetBrains 2019 Annual Highlights] (https://www.jetbrains.com/company /annualreport/2019). After clicking the report, we can find this section.

At this point, the keyword 18650 will be used. Read sections again, and you will find that there is a section whose total number is 18650.

According to the prompt we need to share this section, after clicking the icon to the right of the title, you will see the following

I have found the JetBrains Quest! Sometimes you just need to look closely at the Haskell language, Hello,World! in the hackathon lego brainstorms project https://blog.jetbrains.com/blog/2019/11/22/jetbrains-7th-annual-hackathon/ #JetBrainsQuest https://www.jetbrains.com/company/annualreport/2019/

Keywords: Haskell 、 Hello, World! 、 lego brainstorms

Question 4 Identify the Statement

Enter the link in the prompt or click the Learn more in the picture above to enter the same page, find the corresponding project, you can see the prompt shown in the figure, and use the developer tools to easily copy the content.

It’s easy to see that this is still a paragraph of English and most words are easily recognizable. This reminds me of Hexspeak.

According to the context, “K4r33r2” is a job-related word, and there are consecutive identical letters like “33”. It is natural to guess that it is careers. The remaining word is difficult to guess. Continue thinking, you will find that the law of letter and number substitution is the same, so it can be known from reasoning that “KW357” should be quest
