> This PR optimizes `BigInteger.pow(int)` method. The primary enhancement in > `pow()` is not concerned most on execution time, but rather in memory > optimization, because the PR implementation does the "shift of the exponent" > squaring the result rather than the base, so the base is not squared like in > the current implementation, and this permits to save about half of the memory.
