Explain binary exponentiation for computing the value 5¹⁹. Write the right-toleft binary exponentiation algorithm and show its working for the exponentiation 5¹⁹. Also, find the worst-case complexity of this algorithm

### Binary Exponentiation for Computing the Value \( 519^n \)

Binary exponentiation, also known as exponentiation by squaring, is an efficient algorithm to compute large powers of a number. It works by breaking down the exponentiation process into a series of smaller multiplications based on the binary representation of the exponent. 

#### Right-to-Left Binary Exponentiation Algorithm

1. Initialize Variables:
   - Set `result` to 1 (this will hold the final result).
   - Set `base` to the number we want to exponentiate (e.g., 519).
   - Set `exponent` to the power to which the base is raised.
