First post the fourth Link Linux Interest Group 2016 free question four off

Four-off:

Go to the URL we see is 4 cards K, what does this mean?

You want me to fight the landlord? OK, still obediently look at the source code first.

But nothing was found. No way, the four photos are downloaded to see, but left to see right or a picture ah, it will not be hidden in the content of the picture? How to view the picture content? Find a hex editor!

These actually can, everybody chooses because I am familiar with the Linux operating system HexEdit, downloaded a hexedit to analyze. There's no way, just one card. Sunshine always after the wind and rain, the opportunity appears in the third picture, see what happened to the magical thing!

What the!! This is a RAR compressed file, so immediately modified the suffix of the picture, sure enough to find ...

Then look at the content of 1.txt, found that it seems to be a C language-related programs, but see the content is not the source Ah, modify an. exe to try? The results appeared:

Oh, my God! Snake, all right, like my hand-stump party, 10 minutes later ...

Get Important Message

Then thought that got the whole world, to submit, the result is not right, this is embarrassing, then what should be done now? There is no way, or 又回到最初的起点 , think of what is bad? Suddenly feel that if the card is to hide the file, then why must choose K, and chose K Why is the square piece K is only a file, is there any other meaning?

So Baidu a bit of poker K

The Emperor Caesar? What do you mean? What does that have to do with submission? In front of the snake gave important information, as if what string, eventually found

So how many are we going to move? Write a little program and run.

#include <stdio.h>Charsource[ -] ={' V ',' H ',' U ',' U ',' E ',' F ',' U ',' D ',' I ',' X ',' Q ',' H ',' U '};intline =1;voidFindanswer (intBegin) {Chartest[ -];intI,j,k; for(i = Begin,j =1; J <= -; ++i,++j) {Test[j] =' A '+i% -; }printf("%2d:", line++); for(k =0; k < -; ++k) {printf("%c", test[source[k]-' A '+1]); }printf("\ n");}intMainintargcChar*argv[]) {intI for(i =1; I <= -; ++i) {findanswer (i); }}

Altogether 26 results are as follows

There is no way to paste, but look carefully to find that only the tenth one is meaningful, yes
