WebFeb 20, 2024 · Efficient Approach: The above approach can be optimized based on the following idea: Observation: Sort the array arr[] and it will always be better to take X coordinate’s as subarray of size N / 2 from sorted array A[] and Y coordinates as leftover elements. The answer can be tracked for all subarrays of size N / 2 by using the sliding … WebA similar member function, upper_bound, has the same behavior as lower_bound, except in the case that the set contains an element equivalent to val: In this case lower_bound returns an iterator pointing to that element, whereas upper_bound returns an iterator pointing to the next element. Parameters val Value to compare.
