You will be given two numbers `m,n`. The numbers could span from `0` to `10000`. We can get their product by using binary reduction as show in the table below.
Example (to understand the table please read the description below it) 





real value of m(r)
m

(r*n)

960



Above, we are given two numbers `100` and `15`. we keep reducing the bigger number by dividing it by `2` and hold the integer part of the division till it is no more divisible by `2`. Then we assign the real values to these reduced parts of `m`. Any reduced number `[1,m]` has real value of `0` if it is even, and it will have real value of `1` if it is odd. On the other hand the smaller number in this case `n` keeps on doubling itself the same amount of times `m` reduces itself. The idea of this method is to change multiplication of two big number to a sequence of multiplication by `0` or `1` and perform addition to get the final product. You can see that from the last column `(r*n)` above. 
if we sum the last column we get `0+60+0+0+480+960=1500=100*15`
Now your task for this kata will be to get those non-zero number in the last column in an array and return it sorted in descending order.so for the above example the return will be `[960,480,60]`.

_Beware: _`m,n`_ are not necessarily ordered._
