Implement Sorting algorithms of bubble insertion and selection sort
Linear Sort
HereDATA is anarraywith Nelements. This
Algorithm A2: (Linear Sort)Linear(DATA,N)
- Repeatstep2and 3 forK=1 to N-1
- Set PTR :=K+1 [Initialize pass pointerPTR]
- Repeat whilePTR£ N [Execute Pass](a).IfDATA[K]> DATA[PTR], then:
Interchange DATA[K] andDATA [PTR][End ofIfstructure]
(b)Set PTR: =PTR+1
[End ofinnerloop]
[End ofstep 1 outer loop]
- Exit
SelectionSort
Selectionsortperformssortingbyrepeatedlyputtingthelargestelementintheunprocessedportion of thearrayto the end ofthe unprocessedportion until the whole arrayis sorted.
Algorithm A2: (Selection Sort) SELECTION(A,N)This algorithm sorts thearrayA with Nelements.
- Initialize aloop:
For(i =0;i <N; i++)SetMIN:=A[i]
- Initialize anotherloopFor(j =i+1 ; j<N ; j++)
If (MIN >A[j])
SWAP(MIN,A[j])
- Exit

Algorithm A3: (Insertion Sort)INSERTION (A,N)This algorithm sorts thearrayA with Nelements.
- SetA[0]:=-~.[Initializes sentinel elements].
- Repeat Steps 3 to 5 forK=2,3,….,N:
- Set TEMP:=A[K] andPTR:=K-1.
- Repeat whileTEMP<A[PTR]:
- SetA[PTR+1]:=A[PTR].[Moveselement]
- Set PTR:=PTR-1.[End ofloop].
- SetS[PTR+1]:=TEMP.[Insertselement in proper][End ofStep 2 loop.]
Bubble Sort
Sort bycomparing eachadjacent pairofitems in alist in turn, swappingtheitems if necessary,andrepeatingthe passthrough the list until no swapsaredone.
Algorithm A4: (BubbleSort) BUBBLE(A, N)This algorithm sorts thearrayA with Nelements
- Repeatsteps2 &3 fork =1 toN-1
- Set PTR:=1
- Repeat whilePTR<=N-k
- (a)Ifdata[PTR]>data[PTR+1],thenInterchangedata[PTR]anddata[PTR+1][End ofif structure • (b)Set PTR=PTR+1
- Exit
