Question:
This challenge is a simple calculation.
When you click on the link below you will get a number.
The calculation is:
Example with number 1500:
In this example 4252 is the answer...answer like this: prog2.php?solution=4252
You must do this within 2 seconds. If the answer is correct, you will get the password.
answer:
처음엔 걍 c로 만들어서 2초안에 넣어볼라고 쇼를 했다.
내타수가 그렇게 느린줄 몰랐다. 세상에 만만한거 하나 없더라.
뭘로 해볼까 하다가 만만한 자바 스크립트로 했는데 막상 해볼려니
이것 또한 시간을 꽤나 잡아먹었다.
