Webargpartition(a, k) function in numpy rearranges indices of input array a around the kth smallest element, so that all indices of smaller elements end up to the left, and all indices of bigger elements end up to the right. Not needing to sort all elements saves time: argpartition takes O(n) time, while argsort takes O(n log n) time.
