Pow(x, n)

MediumMath

Implement pow(x, n), which calculates x raised to the power n.

Example:

Input: x = 2, n = 10
Output: 1024

Input: x = 2, n = -2
Output: 0.25
Explanation: 2^(-2) = 1/2^2 = 1/4 = 0.25

Constraints:

  • -100.0 < x < 100.0
  • -2^31 <= n <= 2^31 - 1
  • n is an integer
  • x is not zero when n is negative
