yeah interval tree and binary indexed tree is a one solution which will
give you answer in log(n) time for each query ,but if i got all the
interval at the beigning of time i can get solution in O(1) time by O(n
) preprocessing take array f initialize with zero,now for each
interval(l,r) do
typo mistake take prefix sum of f and see each index value...continue

There are n Intervals. Given a set of m numbers, tell in how many
intervals does each number exists.
Example: 4 Intervals: [2,3] [3,4] [1,4] [3,10]. Numbers
