Multi-key quicksort
Hi,

I have reverted your change to the Multi-key quicksort article. As the note b states, the pseudocode expression denotes a subarray of   from index (inclusive) to (exclusive), which corresponds to mathematical notation for including-excluding intervals (see Interval (mathematics)). --CiaPan (talk) 08:33, 28 February 2017 (UTC)
