Range constructor 
X(i, j) X a(i, j); [i,j) is a valid range. 
Creates an associative container that contains all of the elements in the range [i,j). The comparison object used by the container is key_compare(). 
size() is equal to the distance from i to j. 
Range constructor with compare 
X(i, j, c) X a(i, j, c); 
[i,j) is a valid range. 
Creates an associative container that contains all of the elements in the range [i,j) . The comparison object used by the container is c. 
size() is equal to the distance from i to j. 
Insert with hint 
a.insert(p, t) 
p is a nonsingular iterator in a. 
Inserts t into a. The argument p is a hint: it points to the location where the search will begin. The return value is a dereferenceable iterator that points to the element that was just inserted. 
a contains an element whose key is the same as that of t. The size of a is incremented by 1. 
Insert range 
a.insert(i, j) 
[i, j) is a valid range. 
Equivalent to a.insert(t) for each object t that is pointed to by an iterator in the range [i, j). Each element is inserted into a. 
The size of a is incremented by j – i.
