C++ 20ms solution using priority_queue

  • 0

    As title indicates, I use priority queue to solve this one, actually, my solution is quite like "sort pair according to sum of pair <u, v>, where u belongs to nums1, v belongs to nums2." In another words, if you remove the constraints of k, then my solution could be extended to some problem like "pair sort".
