HackerRank Python Solution - Math Topic - Power - Mod Power

• 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 a^b as 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. It is uncommon to use math.pow().

Task:

• You are given three integers: a, b, and m. Print two lines.

• On the first line, print the result of pow(a,b). On the second line, 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

Solution:

a,b,m = (int(input()) for _ in range(3))

print(pow(a,b),pow(a,b,m),sep='\n')
