Extracting max element Given the array A: Divide and conquer Another common approach.

The free list must be doubly linked in order for this deletion to run in O 1 time. We need to show that if the red-black tree solutionns persistent, insertion can still be done in O lg n time. This can be done just as for insertion, travers- ing a path from the increased node toward the root.

Corrected an error in the substitution method for recurrences on page Let z be the smallest value in L that is greater than y. Choose an underlying data structure. Solve this recurrence by substitution: For example, graph algorithm running times are usually expressed in terms of the number of vertices and the number of edges in the input graph.

By the loop invari- ant, A[1. Might need to use dif- ferent constants for each.

Augmenting Data Structures If search goes left: Consider the treatment of subproblems by the two approaches. Solution to Exercise 9.

Getting Started Solution to Exercise 2.

In other words, each iteration of the while loop of lines 5—7 corresponds to the elimination of one inversion. No key comparisons are necessary. Added the solution introduciton Problem The computation of v[x] is straightforward. To delete object x with key k, assuming that this object is in the dictionary, we need to break the validating cycle. We have shown that every inversion implies one merge-inversion.

## CHEAT SHEET

They are inverses of each other. The running time depends on the number of iterations of the for loop of lines 2—4.

Recurrences Solution to Exercise 4. Increasing key value Given algoritgms S, element x, and new key value k: We will use this technique when we analyze recursive algorithms.

Min-priority queues are imple- mented with min-heaps similarly. Use optimal substructure to construct optimal solution to problem from optimal solutions to subproblems.

Assume for the purpose of contradiction that there is no point of maximum overlap in editikn endpoint of a segment.

This happens if each one is better than all who came before. The binary-search-tree property must hold after the change. The recursion bottoms out on these single-element subproblems. Yo loop invariants is like mathematical induction: We use a hash table when we do not want to or cannot allocate an array with one position per possible key.

Interval i has low[i], high[i].
