Suppose that we randomly choose n numbers as the input to inser- tion sort.

Idea behind linear-time merging: Same argument applies to p2. As in quicksort, a given pair ri and b j is compared at most once.

Convention is to use lg within asymptotic notation, unless the base actually matters.

There are two cases: On small inputs, insertion sort may be faster. Once we understand how to compute m[x], it is straightforward to compute o[x] from the information in x and its two children.

Corrected an error in the solution to Exercise Introdudtion heapsort is a great algorithm, a well-implemented quicksort usually beats it in practice. Taking logarithms of both sides gives an equivalent condition: The randomized algorithm thus takes at least as much time on average as the corresponding deterministic one. Delete all the other children of the randomized node and splice out the randomized node itself.

Arrows go from larger elements to smaller elements, based on what we know after step 4.

Will see how to maintain without increasing O lg n time for insert and delete. Extract the fractional part of k A. Then new x is made black in the last line. We can say this more precisely, as follows: In some cases, the design will be intermixed with analysis. Depends on the problem being studied.

Sorting in Linear Time Bucket sort Assumes the input is generated by a random process that distributes elements uni- formly over [0, 1. After splicing out a node, go up from there to update f. Binary Search Trees Example: The leaves are labeled with a unique matching of jugs. The operations on the dictionary work as follows: Lecture Notes for Chapter All leaves are empty nil and colored black.

Thus, radix sort of d digits, which sorts on digits 1.

### Introduction to Algorithms study group

To show this more formally, draw a binary tree of the comparisons the algorithm does. Because we are dealing with subproblems, we state each subproblem as sorting a subarray A[ p. We assume that the range of a single digit is constant.

Finding the maximum element Getting the maximum element is easy: Chapters 24 and 26; index. Hash Tables Solution to Exercise Solving the merge-sort recurrence: So compute in order of increasing j.

## CHEAT SHEET

Thus, any decision tree for sorting S must have at least k! We have included lec- ture notes for one starred section: The last part shows that the subarrays are merged back into A[ p.

When the loop terminates, the invariant—usually along with the reason that the loop terminated—gives us a useful property that helps show that the algorithm is correct. Worst-case analysis We will prove that a worst-case split at every level produces a worst-case running time of O n 2.
