We are optimizing the quicksort partitioning step in a low-latency trading engine where arrays contain a huge number of duplicate keys (e.g. 0s, 1s, and 2s representing order statuses). Standard Lomuto or Hoare partitioning degrades to O(N^2) when all elements are ...Read more

We are running a low-latency packet ring buffer service in C++ and Go. Whenever an offset wraps around, we need to rotate a large integer array (up to 10 million elements) by k positions to the right. The standard way people ...Read more
