Russian Peasant Algorithm

#challenge

The russian peasant algorithm is an algorithm to do multiplications in a headache less fashion.

Let's make a code to do multiplications using the russian peasant algorithm. Hint: bitwise shift operators(<< , >>) can be useful. Same with &1 even/odd biwise trick. oops too much info given.

make a two columns table and put numbers in first row in each column, numbers that you want to multiply.
first column is doubled and second column is halved at every iteration. the second column number is always floored. each row contains the result of those iterations
keep iterating until the second column number is 1.
discard all the rows where the number in column 2 is even.
sum all other rows in column 1. the total is the result of the multiplication between the two original numbers.

My solution:

NOTE: I did not use the bitwise shift operator hint.

Enter Number 1:
Enter Number 2:
