Tally a multiset

A multiset<int> named ms already holds the values 2, 5, 2, 8, 5, 2. Print each distinct value exactly once, in ascending order, one per line, in the form: the value, a space, the letter x, and the number of copies (no space between x and the number). Every line ends with a newline, including the last one.

Expected Output:

2 x3↵
5 x2↵
8 x1↵

= newline. The output ends with a newline — print one after the last line.
