    50 - Pow(x, n)\. Medium Implement [pow(x, n)](http://www.cplusplus.com/reference/valarray/pow/), which calculates `x` raised to the power `n` (i.e., xn). **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 = 1/22 = 1/4 = 0.25 **Constraints:** * `-100.0 < x < 100.0` * -231 <= n <= 231-1 * -104 <= xn <= 104
