  //     original by: Kevin van Zonneveld (https://kvz.io)
  //          note 1: Returns 1-based insertion index after the last <= target element, like Julia searchsortedlast.
  //       example 1: searchsortedlast([1, 3, 5, 7], 4)
  //       returns 1: 2
  //       example 2: searchsortedlast([1, 3, 5, 7], 0)
  //       returns 2: 0
  //       example 3: searchsortedlast([1, 3, 5, 7], 9)
  //       returns 3: 4
