Unifying End of Line character format and fixing broken links

We unified the format of the End of Line character sequence used in the textarea field inside the Sphere Engine Problems Editor. Until now we alternately used the UNIX-style newline sequence (\n) and the Windows-style one (\r\n). From now on it’s UNIX-style everywhere.

We identified and fixed a few mistakes in the documentation of the Sphere Engine Problems API (both version 3 and version 4).

All the broken links in the contextual help of the Sphere Engine Problems Editor have been fixed - now they point correctly to the appropriate pages of the Problem Setter’s Handbook. We are sorry for any inconvenience caused by these broken links.

At Sphere Engine we combine years of experience in recruiting developers and assessing coding skills with the latest technologies. Our APIs and software components enable creating programming challenges, online compilers, IDEs, and teaching coding to millions of end-users across the globe. We work with companies like Infosys, Amazon, Edhesive, support thousands of educational institutions around the world, and run our own community-focused platforms - Spoj and ideone.
