If you check the website indicated, it's a slight variation on that:

"Your task is to count for k=1,2,…,nthe number of ways two knights can 
be placed on a k×kchessboard so that they do not attack each other."

The input is n (an integer that can range from 1 to 10000), the output 
is a single integer for each value from 1 to n, one per line, the memory 
limit is 512MB, and the maximum runtime is 1.00 seconds.
