Think and Compute

Mr. Garg is challenging you to write a program that takes two non - negative integers $X$ and $Y$ as an input and output a single non - negative integer $Z$, which is equivalent to $X' * Y'$. $X'$ and $Y'$ satisfy the following two conditions: - $X = X' + Y'$, - $Y = X' \oplus Y'$, where $\oplus$ is bit-wise exclusive or. Since $Z$ can be large, output $Z$ modulo 1000000007 ($10^9 + 7$
