Binary exponentiation, also known as exponentiation by squaring, is a technique for Binary exponentiation, also known as exponentiation by squaring, is a technique for
efficiently computing the power of a number. By repeatedly squaring x and halving n, efficiently computing the power of a number. By repeatedly squaring x and halving n,
we can quickly compute x^n using a logarithmic number of multiplications. we can quickly compute x^n using a logarithmic number of multiplications.
