use other STL containers vectorcint and unordered_map to count the frequency of each number. (a) Copy and paste your codes below. (b) What will be the problem if we use container vector? (c) What will be the advantage of unordered mapcint, int over mapcint int? Given a list of random integers, A sample run of the Given random numbers-[1, 1, 2, 2, 3, 3, 3,4,5,7,7,7,7,8,9,9,1,1,6 (a) The map for the frequency of each numbers is [1:4, 2:2, 3:3, 4:1, 5:1, 6:1,7:4,8:1,9:2 (b) The inverted mapcint, setcint>to print out these numbers in the decreasing order of their frequencies. 3: (3 2: 12,9 1: 14, 5,6, 8 (c) The mode is (1, 7]
