Suppose you are given a vector some arrangement of the numbers 1, 2 and 3, for example (1, 2, 2, 2, 1, 3, 3, 1} 2 Write a function which returns the mode of a such a vector, the most common element. (It might be that none of 1,2,3 is more common than the other, in which case you can return any of them.) This function tries to reverse a vector, but it doesn't work. void reverse(vector & v) { for(int i=8, j = v.size()-1; Suppose you are given a vector some arrangement of the numbers 1, 2 and 3, for example (1, 2, 2, 2, 1, 3, 3, 1} 2 Write a function which returns the mode of a such a vector, the most common element.
