http://www.spoj.com/problems/KQUERY/ Getting runtime error repeatedly..Is it because of memory limit exceeded?? Or an invalid memory access(arrayindex out of bound exception) ?? BTW, the approach I used here is  A segment tree where each node stores an sorted interval. For a query i then join different disjoint intervals and then i perform a binary search over the newly formed interval to get number of elements which are greater than k. asked 24 Dec '14, 19:09

can anyone help??
