King Wang

1 月 3, 2022

Shared yesterday How to participate JetBrains Decryption task to get the real family bucket exchange code . today JetBrains Continue in the morning Twitter Launch the second mission :

file

below , Let’s continue to join in , For our authentic JetBrains The family lives on !

Clues to a :Twitter

The first clue is easier , It is not difficult to find out by observation ,Twitter The words in the push string are inverted !

therefore , Let’s write a little program to deal with :

@Test
public void jetbrains() {

String str = ".spleh A+lrtC/dmC .thgis fo tuo si ti semitemos ,etihw si txet nehw sa drah kooL .tseretni wohs dluohs uoy ecalp a si ,dessecorp si xat hctuD erehw esac ehT .sedih tseuq fo txen eht erehw si ,deificeps era segaugnal cificeps-niamod tcudorp ehT" ;
String[] split = str.split(" ");
String result = "";
for (int i =0;i < split.length;i++) {

result += new StringBuffer(split[i]).reverse() + " ";
}
System.out.println(result);
}

Get the following :

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

It doesn’t seem right , The sentence is opposite ! Change the algorithm above :

@Test
public void jetbrains() {

String str = ".spleh A+lrtC/dmC .thgis fo tuo si ti semitemos ,etihw si txet nehw sa drah kooL .tseretni wohs dluohs uoy ecalp a si ,dessecorp si xat hctuD erehw esac ehT .sedih tseuq fo txen eht erehw si ,deificeps era segaugnal cificeps-niamod tcudorp ehT" ;
String[] split = str.split(" ");
String result = "";
for (int i = 0;i < split.length;i++) {

result += new StringBuffer(split[split.length - 1 - i]).reverse() + " ";
}
System.out.println(result);
}

The complete sentence is as follows :

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.

Clues to the second :The product domain-specific languages

Continue to think about another hint of clue one : I can’t see… On a white background , need Cmd/Ctrl+A help !

file

You can see that there is something in the blank space , We choose to copy it out :

This is our 20th year as a company,

Annual report, sharing the section with
18,650 numbers will progress your quest.

Three clues :20 Annual report

It’s been a long time , Later, I read online that NIMA is an English version of Martian , Roughly find some corresponding relations mainly because the shape of characters is similar to that of actual letters 、 Similar pronunciation and other rules , such as :1=i、3=e、0=O、7=t…, This is what Lian mengdai guessed :
