Qn - Pow(x, n)

Pow(x, n)

Question

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

Example 1

Input: x = 2.00000, n = 10 Output: 1024.00000

Example 2

Input: x = 2.10000, n = 3 Output: 9.26100

Example 3

Input: x = 2.00000, n = -2 Output: 0.25000 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.

• Either x is not zero or n > 0.

• -10^4 <= x^n <= 10^4
