1 Sorting: part 1 Barak Obama on sorting, bubble sort, insertion sort,
selection sort, merge, merge sort, ... demos, demos, demos …

2 Sorting, what’s that then?
Given a collection of data, get it into order …

3 Given a collection of data, get it into order …
This is NOT in order

4 Given a collection of data, get it into order …
This is IS in order

5 Given a collection of data, get it into order …
This is IS in order It’s in ascending order

6 Sorting is the process of going from this
to that

7 Who cares? Sorting, why bother? You can find things quicker!

8 You can find things quicker! Use “binary search” (or even linear search and stop early)

137 sorting Show me more! different sorting algorithms and relative performance a beauty contest what is the “sound” of sorting? can you show me it by mime? Expressive dance? Bubble Sort

138 sorting NOTE to self: Bubble sort is a quadratic time algorithm. If I have to sort a data set of N objects the run time will be proportional to N2 To sort 10 numbers will take 100 units of time To sort 100 numbers will take 10,000 units of time Bubble Sort

153 merge sort sorting msort(L) if (size(L) <= 1) return L return merge(msort(leftHalf(L)),msort(rightHalf(L))) Divide and Conquer divide: divide input data into smaller parts recur: solve the small parts conquer: combine the subproblems once solved (merge)

190 merge sort sorting n 2.T(n/2) n/2 n/2 T(n) is time to cut the data into 2 parts make 2 recursive calls to msort merge the 2 msorted parts and this is linear in n

191 merge sort sorting n n/2 n/2 n/4 n/4 n/4 n/4

192 merge sort sorting n n/2 n/2 4.T(n/4) n/4 n/4 n/4 n/4

194 merge sort sorting n n/2 n/2 n/4 n/4 n/4 n/4 8.T(n/8) n/8 n/8 n/8 n/8 n/8 n/8 n/8 n/8

195 merge sort sorting n n/2 n/2 n/4 n/4 n/4 n/4 8.T(n/8) n/8 n/8 n/8 n/8 n/8 n/8 n/8 n/8 This goes on h times where h = log(n) … base 2

196 merge sort sorting n n/2 n/2 n/4 n/4 n/4 n/4 8.T(n/8) n/8 n/8 n/8 n/8 n/8 n/8 n/8 n/8 This goes on h times where h = log(n) … base 2 Therefore O(n) at each level

197 merge sort sorting n n/2 n/2 n/4 n/4 n/4 n/4 8.T(n/8) n/8 n/8 n/8 n/8 n/8 n/8 n/8 n/8 This goes on h times where h = log(n) … base 2 Therefore O(n) at each level Therefore O(n.log(n))
