Question-2:
A pyramids are discovered, each has a triangular base with equal sides. An n meters high
pyramid is constructed by forming n layers of triangles using Im' cubical stones. Then layers are
stacked on top of each other. The first layer is the triangle with n meters base, on top, n-1 meters
base, until the top level which has only I stone. You are asked to calculate the number of stones
needed to builda pyramid with the height n.
WAIT! We just discovered that some pyramids have a secret room inside. This room is also of
the same shape and structure as the pyramid with m layers of stones removed. In order for the
room to be secret, m<n-2.
Figure L. (a) 6 layers of stones, and (b)6meters high pyramid.
Example
The total number of stones needed to build a 6 meters high pyramid is
-(1+2+3+4+5+6)*(1+2+3+4+5)-(1+2+3+4)+(1+2+3)+ (1+2)+ 1
-21+15 10+6+3+1-56.
If this pyramid has a 2 meters high secret room, then the total mumber of stones neoded is 56-4
52.
Input
You have to read data from input file named, "input.txt". Each input has twe integers, the finst
represents the pyramid height n, and second represents the secret room height m Input is
terminated by a sequence having n 0, m-0which should not be processol
