Compute the expected value of the next step of a sorted random walk
@Barry: I am sorting deterministically, taking the earliest case of a value first. That is, if $S_i = S_j$ and $i<j$ , then $S_i$ appears before $S_j$ in the sort order.

Compute the expected value of the next step of a sorted random walk
@Barry: For N=4 , there are four expected values to compute. The expected step after the "smallest" position is 12/16 ; the expected step after the "second smallest" position is 2/16 ; ...; the expected step after the "largest" position is 10/16 . Does that make sense?
