A permutation on the set {1, . . . , k} is a one-to-one, onto function on
Question:
A permutation on the set {1, . . . , k} is a one-to-one, onto function on this set. When p is a permutation, pt means the composition of p with itself t times. Let
Show that PERM-POWER ∈ P. Note that the most obvious algorithm doesn’t run within polynomial time. First try it where t is a power of 2.
