Hello coders, In this post, you will learn how to solve Power and Mod Power in Python HackerRank Solution. This problem is a part of the Python Hacker Rank series.
Power and Mod Power in Python HackerRank Solution
problem
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

# Enter your code here. Read input from STDIN. Print output to STDOUT a, b, m = [int(input()) for _ in range(3)] print(pow(a, b), pow(a, b, m), sep='\n')
