Design and Analysis of Algorithms - Old Questions

1.  Use RAM model to estimate the big-oh of the running time for following code segment.

for(i=0;i<n;i++){

                             small pos = i;

                                    smallest = Array[small pos];

                                    for(j=i+1; j<=n; j++){

                                    if(Array[j]<smallest){

                                                small pos = j;

                                                smallest=Array[small pos];

                                    }

            }

            Array[small pos]=Array[i];

            Array[i] = smallest;
