A circle of radius $R$ cm is touching both the positive axes i.e., the X-axis and the Y-axis. There is another circle touching both the axes as well as the previous circle. Note that this circle won't have the same centre as the original circle .Find the sum of squares of the radius (in $cm^2$) of all the circles that satisfies the above condition. ###Input: - The first line contains a singl
