[Discrete math]

Show that it is possible to arrange the numbers 1, 2, . . . , n

in a row so that the average of any two of these numbers

never appears between them. [Hint: Show that it suffices

to prove this fact when n is a power of 2. Then use mathematical

induction to prove the result when n is a power

of 2.]

I saw the solution but I don't understand why permutation pi is using here.. please explain it with more detail.

Discrete Math answer question 2 only 1) You have 10 identical snails you want to feed to your 4 starfish (named SFA, SFB, SFC, and SFD). a. One way to distribute the snails is to give 3 snails to SF-A, 2 snails to SF-B, 0 snails to SF-C, and 5 snails to SF-D. How would you represent this outcome as a stars-and-bars diagram? b. How many ways are there to distribute the snails all together? Briefly explain. c. How many...
