Answer to Question #258488 in Algorithms for JONIE

Question

Let b is a real number. Let n be a non -negative integer. Assume b and n are not

simultaneously 0. Write iterative and recursive functions that return value of b n, the nth power of b

Answer 1

Iterative function:

function poweri(b, n)
Let res = 1
For i from 1 to n do
    let res = res * b
Next i
Return res

Recursive function:

function powerr(b, n)
If n equal 0 
    Return 1
Let res = power(b, n-1)
Return res * b
