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 ab as shown below:
>>> pow(a,b) 
or
 
>>> a**b
It's also possible to calculate ab 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')
