Compares the contents of two unordered containers.
The contents of two unordered containers lhs and rhs are equal if the following conditions hold:
- lhs.size() == rhs.size().
- each group of equivalent elements
[lhs_eq1,lhs_eq2)obtained from lhs.equal_range(lhs_eq1) has a corresponding group of equivalent elements in the other container[rhs_eq1,rhs_eq2)obtained from rhs.equal_range(rhs_eq1), that has the following properties:
