//Desc: Array Split
//Say you have an array (or list) of arbitrary integers. 
//The data structure must be reordered so that all values less than a 
//special reference value are placed on the left. All values greater than 
//or equal to the reference value are placed on the right. 
//The ordering within the subranges is not relevant and may vary.

//Input                         Reference element   Sample result
//[4, 7, 1, 20]                     9               [1, 4, 7, 9, 20]
