DIY: Pow(x, n)
Solve the interview question "Pow(x, n)" in this lesson.
We'll cover the following
Problem statement
For this problem, you are given an integer base
and power
value. You have to implement the pow()
function, which will raise the base
to a specified power and return its value.
Assume the following constraints:
- -100 <
base
< 100 - - <=
power
<= -1 - - <= <= , where
x* is the
baseand *n* is the
power`.
Input
The pow()
function will take two inputs: base
and power
, and it will call the quickPow()
function recursively, which will take two inputs: base
and power / 2
. Here is an example of the inputs:
base = 2
power = 4
Output
The pow()
function returns the base
raised to a specified power
. The following is the output of the inputs shown above:
