Get problem statements PDFs from AtCoder, Codeforces, SPOJ

How to use

Go to the problem page, open the developer tools (F12 in Chrome), go to console, and paste the respective payload below, this will allow you to print the problem statement (you can then select to print it to PDF). All of these preserve images.

These codes delete the prefix letter of the problem since they might cause users to guess the difficulty of the problem, to make this completely effective, make sure to turn off printing "headers and footers".

AtCoder

var x = document.getElementById('main-container').children[0].children[1].children[0].innerText; // title
x = x.substr(x.indexOf('-') +  2);  // remove letter code for this problem
x = x.substr(0, x.length - " Editorial".length);  // removes word " Editorial" from the title
// time/memory limits
var limits  = document.getElementById('main-container').children[0].children[1].children[4].innerText;
var y = document.getElementById('task-statement').children[0].children[1]; // content
y.removeChild(y.children[0]); // Hides problem score
document.body.innerHTML = '<h1>' + x + '</h1>' + limits + y.innerHTML;
// change web page title so that when saving as a PDF, the problem letter does not show up in the file name
document.title = x;
window.print();

Codeforces

var x = document.getElementById('pageContent'); // All of the problem statement
var y = x.children[2].children[0].children[0].children[0].children[0].innerHTML; // only the title of the problem like "A - eqweqwe"
x.children[2].children[0].children[0].children[0].children[0].innerHTML = y.substr(y.indexOf('.') + 2); // replace the title for only "eqweqwe"
document.body.innerHTML = x.innerHTML;
window.print();

SPOJ

var x = document.getElementById('problem-name').innerHTML;
var y = document.getElementById('problem-body').innerHTML;
document.body.innerHTML = '<h1>' + x + '</h1>' + y; 
window.print();

Problems

• For SPOJ, it doesn't report the time and memory limits, since I'm planning on using vjudge, and that tells you those limits, I plan on getting people watch the limits from there, but you get the idea of how to extend this if you want to, I would, of course, welcome PRs.

• I need support for other OJs, feel free to add yours.
