Yоu аre аnаlyzing a large dataset оf n server respоnse times represented as an unsorted vector of integers. Your task is to find the sum of the k smallest response times. Write a C++ function called sum_k_fastest that accepts response times in a std::vector and an integer k as parameters, and returns the sum of the k fastest response times. The function must have a runtime of O(n log(k)). You may use the C++ implementation of max-heap. Example: Input: times = [12, 5, 20, 8, 15], k = 3Output: 25Explanation: The 3 fastest (smallest) response times in the dataset are 5, 8, and 12. The sum of these times is 25. Note: You may not use any other STL functions other than std::priority_queue functions and standard std::vector access functions.
