50. Pow(x, n)

PreviousCODENextCODE

Last updated 2 years ago

Medium

Implement , 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

pow(x, n)
