Problem 1203. Reference Index Number
Given a reference set R of elements (each unique but identical in type), and a list V of elements drawn from the set R, possibly with duplicates, return K such that R(K) == V. The elements of R may be numeric or string.
For example, refIndex(9:-1:5,[7 5 6 5]) should return [3 5 4 5].
