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