Let P = (p1,...,pn) be a permutation of [n]. We say a number i is a fixed point of p, if pi = i. (a) Determine the number of permutations of [6] with at most three fixed points. (b) Determine the number of 9-derangements of [9] so that each even number is in an even position. (c) Use the following relationship (not proven here, but relatively easy to see) for the Rencontre numbers: Dn =(n-1)-(Dn-1 +Dn-2) (∗) to perform an...

C# Palindrome Permutation: Given a string, write a function to check if it is a permutation of a palindrome. A palindrome is a word or phrase that is the same forwards and backwards. A permutation is a rearrangement of letters. The palindrome does not need to be limited to just dictionary words. Input: Tact Coa Output: True (permutations: "taco cat", "atco cta", etc.) Comment your code to explain it.
