 BUBBLE SORT BUBBLE SORT  INSERTION SORT INSERTION SORT  SELECTION SORT SELECTION SORT  RADIX SORT RADIX SORT

 If we compare pairs of adjacent elements and none are out of order, the list is sorted  If any are out of order, we must have to swap them to get an ordered list  Bubble sort will make passes though the list swapping any adjacent elements that are out of order

(done) EXAMPLE OF BUBBLE SORT

STEP 1: Repeat steps 2 and 3 for I=1 to N-1 STEP 2: Repeat step 3 for J=1 to N-1 STEP 3: [Exchange elements] If A[J]>A[J+1] then TEMP:=[J] A[J]:=A[J+1] A[J+1]:=TEMP [end of if statement] [end of step 2 for statement] [end of step 1 for statement] STEP 4: Exit

STEP 1: Repeat step 2 to 4 for I=2 to n STEP 2: Set temp:=A[I] position:=I-1 STEP 3: [move down 1 position all elements greater than temp] repeat while temp =1 set A[position +1]:=A[position] set position:=position-1 [end of loop] STEP 4: [insert temp at proper position] set A[position+1]:=temp [end of step 1 for loop] STEP 5: [finished] Exit

STEP 1: repeat steps 2 to 4 for K=1 to n-1 STEP 2: set min:=A[K] position:=K STEP 3:[make pass and obtain element with smallest value] Repeat for I=K+1 To n if min>A[I] then min:=A[I] and position:=1 [end of if statement] [end of step 3 loop] STEP 4:[exchange elements] if position <> K then temp:=A[k] A[K]:=A[position] A[position]:=temp [end of if statement] [end of step 1 for loop] STEP 5:[finished] exit

 Assuming decimal elements and 10 buckets, we would put the elements into the bucket associated with its units digit  The buckets are actually queues so the elements are added at the end of the bucket  At the end of the pass, the buckets are combined in increasing order

RADIX SORT EXAMPLE  The unit digit is 0  The unit digit is 1  The unit digit is 2  The unit digit is 3

RADIX SORT EXAMPLE(CONTINUED) The unit digits are already in order Now start sorting the tens digit

Values in the buckets are now in order The unit and tens digits are already in order Now start sorting the hundreds digit RADIX SORT EXAMPLE(CONTINUED )
