  //      discuss at: https://locutus.io/rust/splitn/
  // parity verified: Rust 1.85
  //     original by: Kevin van Zonneveld (https://kvz.io)
  //          note 1: Produces at most n fields; the last field contains the unsplit remainder.
  //       example 1: splitn(3, ' ', 'Mary had a little lamb')
  //       returns 1: ['Mary', 'had', 'a little lamb']
  //       example 2: splitn(1, 'X', 'abcXdef')
  //       returns 2: ['abcXdef']
  //       example 3: splitn(3, 'X', 'lionXXtigerXleopard')
  //       returns 3: ['lion', '', 'tigerXleopard']
