Hi! I have an array of doubles that I map to a hashmap to keep track of the indices of the elements. I want to be able to sort the array and still keep track of the indices and thats no problem as long as the elements are distinct. But when I encounter 2 or more elements in the array that are equal my whole scheme fails since they will get the same index. I see two solutions to the problem: 1: Find a way to generate better keys for the elements (dont know how to do this) or 2. Throw out the hashmap and apply a new datastructure that actually does what I want. Anyone got any suggestions on this? Im not to excited about writing my own specific datastructure for this since it's overall a fairly small task that Im working on. Thanks for any help! Slim
