Elements in Range [a, b] | GFG POD | Binary Search Optimization (C++ Solution)

Problem: Count elements in range [a, b] for each query This is a GFG Problem of the Day (POD) — given an unsorted array and multiple queries, count how many elements of the array lie within [a, b] for each query. Efficient Approach: Sort the array Use binary search (lower_bound and upper_bound logic) Answer each query in O(log N) time This beats the naive O(N×Q) approach and is perfect for large constraints.
