Answer 1

So, assume |σ(k)−σ(k+1)|=i,|σ(k)−σ(k+1)|=i, in how many ways can you do this? Well you have 22 options to choose the sign(which one is bigger) and then you can place the smallest one at 1,1, the biggest one at i+1i+1 and take them to the right until the biggest one hits N.N. So, you have 2(N−i)2(N−i) ways to do this. Also, you really do not care about what happens on the other houses, so you just pick a random permutation for the N−2N−2 choices. You can pick this permutation in (N−2)!(N−2)! ways.
