Exchange the contents: Given two glasses marked A and B. Glass A is full of apple drink and glass B is full of grape drink. For exchanging the contents of glasses A and B, represent the state by suitable variables, and write the specification of the algorithm.

Trace the step-by-step execution of the algorithm for factorial(4).
factorial(n)
--inputs: n is an integer, n > 0
-- outputs: f = n!
f, i := 1 ,1
while i < nf
, i := f × i, i+1

Power can also be defined recursively as
\(a^n= \begin{cases}1 & \text { if } \mathrm{n}=0 \\ \mathrm{a} \times \mathrm{a}^{\mathrm{n}-1} & \text { if } \mathrm{n} \text { is odd } \\ \mathrm{a}^{\mathrm{n} / 2} \times \mathrm{a}^{\mathrm{n} / 2} & \text { if } \mathrm{n} \text { is even }\end{cases}\) 
Construct a recursive algorithm using this definition. How many multiplications are needed to calculate a¹⁰?
