Quicksort is one of the fastest general-purpose sorting algorithms used in contemporary code bases. It utilizes the divide-and-conquer technique similar to the merge sort algorithm. Although, the former one depends on an operation commonly called partitioning. The original vector is split on the ...

*Sys is the amount of CPU time spent in the kernel within the process. This means executing CPU time spent in system calls within the kernel, as opposed to library code, which is still running in user-space. Like 'user', this is only CPU time used by the process. ...
