We insert at the rightmost spot so as to maintain the complete tree property. Then, we 'fix' the tree by swapping the new element with its parent, until we find an appropriate sport for it. We bubble up the minimum element. This takes O(logn), where n = number of nodes in the heap. -![Insert in a min heap](img/minheap_insert.png){width="600"} + ### 3.2.

Depending on their values, there's no inherent ordering between the left and right elem, but we need to take the smaller one in order to maintain the min-heap ordering. This also takes O(logn) time. -![extract in a min heap](img/minheap_extractmin.png){width="600"} + ## 4.

While a hash table can quickly look up whether a string is a valid word, it can't tell if a string is a prefix of any valid words.
