You are working on the city construction project. You have A houses in the city. You have to divide these houses into B localities such that every locality has at least one house. Also, every house in a locality should have a telephone connection wire with each of the other houses in the locality.

You are given integers A and B.

Print the minimum and the maximum number of telephone connections possible if you design the city accordingly.

Example

Assumptions

• A = 6
• B = 3

Approach

A minimum number of telephone connections can be achieved if houses were split into localities consisting of 2 houses each. The maximum number can be achieved if localities were split into localities of 1, 1, and 4 houses.

Ans = 3 6
