slide A -> D means skipping B and C and only values on A and D are counted, B and C are not counted and the path length in case you slide A-> D is 2 and when you go A->B->C->D is 4.

direction in which I am thinking is that maybe I could compute max and min rang query matrix and then from both sides start and end somehow figure out the outer boundaries .... but as QM said i see no way to avoid full all-pair traversal of the matrix ... also i am thinking in direction of maybe starting the taversal from the highest value in the matrix and working my way to reach start and end point but i am not sure if this is a good way to go...
