# Problem

Design a class named Box whose dimensions are integers and private to the class. The dimensions are labelled: length l, breadth b, and height h.
The default constructor of the class should initialize lb, and h to 0.
The parameterized constructor Box(int length, int breadth, int height) should initialize Box’s lb and h to length, breadth and height.
The copy constructor Box (Box B) should set lb and h to B‘s lb and h, respectively.

Apart from the above, the class should have 4 functions:

• int getLength() – Return box’s length
• int getBreadth() – Return box’s breadth
• int getHeight() – Return box’s height
• long long CalculateVolume() – Return the volume of the box

Overload the operator < for the class Box. Box A < Box B if:

1. A.l < B.l
2. B.b < B.b and A.l == B.l
3. A.h < B.h and A.b == B.b and A.l == B.l

Overload operator << for the class Box().if B is an Object of class Box:cout<<B should print B.lB.b and B.h on a single line separated by spaces.

### Constraints :

0 <= l,b,h <= 10^5Two boxes being compared using the < operator will not have all three dimensions equal.
