Here is the interview question prompt, presented for reference.

Given a number x and an integer n, find the value of x raised to the power n ( xn ).


For example, consider the following two numbers,

x = 2.1, n = 3

If the number 2.1 is multiplied by itself 3 times, then the answer is 9.261 (rounded to the nearest 100), which is 2.1 raised to the power 3.

Constraints

• -100.0 < x < 100.0
• -231 <= n <= 231-1
• -104 <= xn <= 104
