In the following figure you can see a rectangular card. The width of the card is W and length of the card is L and thickness is zero. Four (x*x) squares are cut from the four corners of the card shown by the black dotted lines. Then the card is folded along the magenta lines to make a box without a cover.
The input file contains several lines of input. Each line contains two positive floating-point numbers L(0<L<10000) and W(0<W<10000); which indicate the length and width of the card respectively.
Output
For each line of input you should give one line of output, which should
contain two or more floating-point numbers separated by a single space. The
floating-point numbers should contain three digits after the decimal point. The
first floating point number indicates the value for which the volume of the box
is maximum and then the next values (sorted in ascending order) indicate the
values for which the volume of the box is minimum.
