The document is a presentation by Abdul Kuddus on sorting elements of an array using the insertion sort algorithm. It explains the concept of sorting, details the algorithm steps, and provides an example to illustrate how insertion sort works. The final result shows the sorted array from an initially unsorted input.
![#Sorting:
Let A be a list of m elements A1 , A 2 , âĻ. An in memory. Sorting A
refers to the operation of rearranging the contents of A. So that they
are increasing in order(numerically or alphabetically) that is ,so that
A1 <=A2 <=A3 <= A4 <= âĻâĻ..<=An
#Insertion sort:
Suppose an array with n elements A[1],A[2]âĻâĻA[n] in the
memory. The insertion sort algorithm scans A from A[1] to A[n]
inserting each element A[k] into its position in the previously sorted
sub array A[1],A[2]âĻ..A[k-1].](https://image.slidesharecdn.com/insertionsort-180914171335/85/Insertion-sort-algorithm-power-point-presentation-3-320.jpg)
![#Algorithm:
Insertion (A,N)
This algorithm sort the array A with N element
1.Set A[0]=1 [initial sentinel element]
2.Repeat steps 3 and 5 for k=2,3,âĻ.N:
3.Set TEMP:=A[k] and PTR:=K-1.
4.Repeat while TEMP< A[PTR]:
(a)Set A[PTR+1]:=A[PTR]. [move element forward]
(a) Set PTR:=PTR-1.
[End of loop]
5.Set A[PTR+1]:=TEMP. [insert element at proper place]
[End of step loop 2]
6. Return.](https://image.slidesharecdn.com/insertionsort-180914171335/85/Insertion-sort-algorithm-power-point-presentation-4-320.jpg)

- 6. *Pass1: using sorting we compare 1st element with its previous nearest large element *pass2: using sorting we compare 2nd element with its previous nearest large element After comparison result of array *pass3: : using sorting we compare 3rd element with its previous large element 77 44 22 6633 11 77 33 44 11 22 6677 33 44 11 22 66 33 77 11 22 66 33 At 77 has no previous large item , so result 77 44 11 22 66 44
