Problem : Power – Mod Power  Hacker Rank solution 

So far, we have only heard of Python’s powers. Now, we will witness them!
Powers or exponents in Python can be calculated using the built-in power function. Call the power function as a^b shown below:

>>> pow(a,b) 

or

>>> a**b

It’s also possible to calculate a^b mod m

>>> pow(a,b,m) 

This is very helpful in computations where you have to print the resultant % mod.
Note: Here, a and b can be floats or negatives, but, if a third argument is present, b cannot be negative.
Note: Python has a math module that has its own pow(). It takes two arguments and returns a float. Frankly speaking, we will never use math.pow().

Task :

You are given three integers: a, b, and m, respectively. Print two lines.
The first line should print the result of pow(a,b). The second line should print the result of pow(a,b,m).

---

Input Format :

The first line contains a, the second line contains b, and the third line contains m.

Constraints :

• 1 <= a <= 10
• 1 <= b <= 10
• 2 <= m <= 1000

---

Sample Input :

3
4
5

Sample Output :

81
1
