"NettetThe purpose of partitioning is to put all the elements <= the value of the pivot to the left of the pivot and all the elements > the value of the pivot to the right of the pivot. In the picture, the pivot has a value of 11. The elements > the value of the pivot (14 and 12) are to the right of the pivot. " - Integer partition algorithm
