1. Identify the arithmetic operation calculated by the following function power. Explain how the target of computation is achieved. What is the computational complexity of the process? Value n/3 computed in the code below is the outcome of the integer division (the integer part of the math division n/3, [n/3] in math notation) of n by 3. Value n mod 3 is the remainder of the integer division of n by 3 (0,1, or 2). function power (n: integer ): integer; var a, b: integer; begin if n
