With only this info and without preprocessing , you need to scan all the N integers in the list atleast once. Hence cannot be better than O(n). If preprocessing is allowed you can compute the answers for all n^2 pairs of x1,x2 and when some one asks , return the corresponding list. In that case it would be better that O(n). !!
