q design odd-even transposition

Question

Q. Design Odd-Even Transposition Algorithm?

Algorithm: Odd-Even Transposition

for I=1 to N

    {      

     If (I%2 != 0) //i.e. Odd phase

           {     

            For j=1, 3, 5, 7,..................2*n/2-1

                    {

                          Apply compare-exchange (P_j, P_j+1)      //Operation is performed in parallel

                    } 

           }              

     else // Even phase

           {     

            For j=2, 4, 6, 8..................2*(n-1)/2-1

                    {

                          Apply compare-exchange (P_j, P_j+1) //Operation is performed in parallel

                    } 

           }

     I++
