Nettet10. okt. 2024 · You can simply amend Hoare's algorithm to return the index of the pivot, re: because Hoare partitioning does not return the index of the pivot necessarily. To do this, you select the first element of your array as the pivot and then you essentially ignore it, partitioning the remaining sub-array arr[1:] as you would normally.
