(45 points) Add these functions for manipulating collections. They are not part of the class Collection.  input operator (reading from a file): istream& operator (istream& is, Collection& c); reads from the istream is pairs in this format: color size (no parentheses or colons, use space to separate them). As colors use strings (you can use STL class string here): red, blue, yellow, green, and as sizes use strings: small, medium, large. You need to read from an input file where each pair is in one line. Use at least two input files: stress_balll.data and stress_ball2.data for two collections. output operator: ostream& operator
