We use a hash table when we do not want to or cannot allocate an array with one position per possible key.

Its a risk, but not too bad if it costs a few bucks. From parts a and cwe know that insertion into a persistent binary search tree of height h, like insertion into an ordinary binary search tree, takes worst- case time O h. If key k is actually stored in Tthen T [k] contains the index, say jof a valid entry in S, and S[ j ] contains the value k. Second method of proving the base case: When we look at the binary search trees resulting from each of the 3!

Hash functions We discuss some issues regarding hash-function design and present schemes for hash function creation.

Changed the exposition of indicator random variables in the Chapter 5 notes to correct for an error in the text. Unfortunately, this scheme does not always run in the required time bound. D T A is the sum of the decision-tree path lengths for sorting all input per- mutations, and the path lengths are proportional to the run time.

Similar argument for min-heaps. When comparing two elements, compare them by their values and break ties by their indices. Any bitonic path ending at p2 has p2 as its right- most point, so it consists only of p1 and p2. Insertion is more straightforward than deletion. Thus, any decision tree for sorting S must have at least k! Solve this recurrence by substitution: Increasing key value Given set S, element x, and new key value k: Since the decison tree must have at least n! Corrected a minor typographical error in the Chapter 22 notes on page We then start scanning the list from the beginning.

The following procedure permutes the array A[1. For interval trees 1. Via very fast search on Google: Getting Started Analyzing algorithms We want to predict the resources that the algorithm requires. So compute in order of increasing j. Then there exists a path from the root to a node at depth h, and the depths of the nodes on this path are 0, 1.

Now we consider the case when n is odd. The procedure com- pares v to the array entry at the midpoint of the range and decides to eliminate half the range from further consideration. In the shortest path, at most every node is black.

Solving the merge-sort recurrence: Because this revision history is part of each revision, the affected chapters always include the front matter in addition to those listed below. The only content changes are on page ; in pages and only pagination changes. The number of nodes is at most 1 plus the sum n of the lengths of the binary strings in the tree, because a length-i string corresponds to a path through the root and i other nodes, but a single node may be shared among many string paths.

Un- like linear probing, it jumps around in the table according to a quadratic function of the probe number: We call this function a hash function. Unless you find some reliable source online, it is best to get the original solutions manual, by any means necessary. The sorting phase can be done in O n lg n worst-case time using merge sort or heapsortand the scanning phase takes O n time.

The last part shows that the subarrays are merged back into A[ p. For the substitution method: Second, if we were to include all solutions, this manual would be longer than the text itself! Scan the sorted list from lowest to highest x-coordinate. The reason for this paper Sorting in Linear Time Take expectations of both sides: Observe that once an element x is chosen as the root of a subtree Tall elements that will be inserted after x into T will be compared to x.

In each of these parts, f n has the form nk. Now, if the median is in X but is not in X[k], then the above condition will not hold. Therefore all ancestors of both z and y must be changed. It has the magnitude of the difference of the two closest numbers in the subtree rooted at x.
