• Count Elements in a Given Range Using Sorting and Binary SearchJun 06, 2026. This problem involves finding the number of elements in an unsorted array that lie within a given range [a, b] for multiple queries. A naive approach would check each element for every query, resulting in high time complexity. A more efficient solution uses sorting and binary search: Sort the array to enable fast searching. For each query [a, b]: Use a lower bound search to find the first element = a. Use an upper bound search to find the first element > b. The difference between these indices gives the count of elements in the range. This approach significantly reduces time complexity to O(n log n + q log n) while keeping space usage minimal. It’s a classic example of combining sorting with binary search to handle range-based queries efficiently.
