Example 1: Input: N = 5 arr[] = {4,1,3,9,7} Output:1 3 4 7 9 Explanation:After sorting elemen At this point, the largest item is stored at the root of the heap. Traverse the given array and generate all possible pairs (arr [i], arr [j]) from the given array and for each pair (arr [i], arr [j]), update the value of totalOR = (totalOR | arr [i] | arr [j]). Below is the implementation of the above approach: C++. Replace it with the last item of the heap followed by reducing the size of heap by 1. close, link Each node has a pointer towards the left child and left child points towards the next sibling of the child. Learn how to pair a compatible collar to your Alpha® 200i using a track or control code.
