Check Membership with count

Write a function bool contains(const set<int>& s, int x) that returns true if x is stored in the set s and false otherwise. Use s.count(x).

The test prints found when your function returns true and not found when it returns false.

Do NOT write a main function.

Expected Output:

found↵
not found↵

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