Hi I have a program which creates permutations for 10 letters, so the values i get is 10 ^10 which is more then 3 million Now i have to go through all 3 million records and do some calculations to determine the best possible combination .
Any ideas what i should use, LinkedList, ArrayList, HashMap, what would be the best way performance wise should i use primitive or objects for calculations. Any suggestions on approaching this problem. Ashish
