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 :
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
Solution :
