A heap is a binary tree that is completely filled in all level, that is, from top to bottom.2 For any element in array position i, the left child is in position (2 + i), where i is the indexof the parent..3. In a min heap, for every node x, the key in the parent of x is smaller than (or equal to) thekey in x. .4. On of the basic operations in heap is delete minimum which deletes the node found onthe leftmost part of the heap.5. Heapify is the procedure for maintaining the heap property when one of the elements ofthe heap is changed.6. A hash function can result in a many-to-one mapping (causing collision)..7. Collisions can be avoided or prevented by using a "good" hash function.8. When the key is a string, it must be converted to an integer. One of these stringconversions is option #1. The probiem with this technique is that anagrams will map tothe same index.9. Radix is a hash function that converts the base-10 integer key into a binary value.10. Linear probing is the best collision resolution technique. One of the reasons is thatclustering of data can be prevented.
