You are tasked with writing a function that takes in a vector of integers and returns a new vector, sorted based on the frequency of the integers in descending order. If two numbers have the same frequency, the larger number appears first. Let's illustrate what we mean by example. In the following examples, we use the notation $[2,4,6]$ to show the composition of a vector. In $[2,4,6],2$ resides at index $0,4$ at index $1,$ and so on$.$
