- * Calculating a^b in O(log(b)) by converting b in binary no.
+ * Calculate a^b in O(log(b)) by converting b to a binary number
  * Binary exponentiation (also known as exponentiation by squaring)
  * is a trick which allows to calculate an using only O(logn) multiplications
  * (instead of O(n) multiplications required by the naive approach).
