Given a number `x`

, complete the program
below named `Power`

that computes the value
of `x`

, where
^{n}`n`

is an integer.
While the value of the double variable `x`

can be positive or negative, the value of the integer
`n`

should be non-negative.

Input: `x`

,
the value to be raised to the `n`

th power.

Input: `n`

,
the value of the power.

Output: `x`

,
the value of ^{n}`x`

raised to the
`n`

th power.
