PivotingStrategyInterface (Macrofocus MOLAP API for Swing SpecificationMOLAP is a Multidimensional, Open-Source, In-Memory, Object-Oriented, and Embeddable API for aggregating datathrough computationally efficient multidimensional cubes developed by Macrofocus. It supports the usualdrill-down, drill-up, slicing, dicing, and pivot operations, alongside a wide choice of built-inaggregation functions, with many additional distinctive features.A good and efficient starting point is the use of the {@link com.macrofocus.molap.dataframe.DataFrameFactory} class. It will get you started within minutes!)

- Method Detail
  - pivotIndex
```
int pivotIndex(double[] work,
               int begin,
               int end)
```
    Find pivot index of the array so that partition and K^th element selection can be made
    
    Parameters:
    
    work - data array
    
    begin - index of the first element of the slice
    
    end - index after the last element of the slice
    
    Returns:
    
    the index of the pivot element chosen between the first and the last element of the array slice
