Number of distinct elements in a range in an array(solving online)
hello everyone,
Recently i came across this problem http://www.spoj.com/problems/DQUERY/en/. I solved the problem using Mo's algo and BST which is basically offline solution. Is there a way I can solve for each query online? If yes, please help me out.
Thanks in advance!!
