If I have a map<string,pair<int,int>> and I want to sort it in three different ways. 1.Sort by key. 2.Sort by value of first element in the pair. 3.Sort by value of second element in the pair.

1.Sort by key:
2.Sort by value of first element in the pair:
3.Sort by value of second element in the pair:
