So in the problem you need to do left shift of elements from starting upto d elements. What you are doing is a brute force approach. Simply print the elements after dth index and then print the element upto d index it will work. Like given below
for(int i=d;i<n;i++) cout<<arr[i]<<" ";
for(int i=0;i<d;i++) cout<<arr[i]<<" "; cout<<"\n";
