Write a function sum_mult(n,v) which takes as inputs a positive integer n and a vector of positive integers v. The output should be the sum of every number less than or equal to n, which is a multiple of at least one of the entries of v. So sum_mult(10, c(3,5)) should return 33 since it is the sum of the numbers 3, 5, 6, 9, 10. (R studio)
