Integer indexing array: Reverse subsets

Construct an indexing array indexArray so that the statement reversedOrder $=$ origOrder$($indexArray$)$; results in a row array beginning at startinglndex down to element $1.$

Ex: If origOrder is $2,8,9,15,3,44,23,25,7,68$ and startingValue is $3,$ then reversedOrder is $9,8,2.$ Row array reversedOrder contains origOrder's element $3,$ element $2,$ and element $1.$
