<h3>OPPOSITE WORDS OF REASSEMBLING</h3>
Answer:
Starting from root, recursively traverse the min-heap. Once we find a key with value less than our X, we know that every key in subtree of that key will be also smaller than our X. Otherwise, we should keep traversing.
Explanation:
The complexity of this algorithm will be O(N) where N is the number of keys in our min-heap.
I think they should join the military.
It is free, so they don't have to think about spending too much money on various courses. And obviously, they will be serving their nation if they are in the military. Online courses won't give them hands on experience, and your other options aren't free.
