Introduction To Python
Python is a widely-used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It was created by Guido van Rossum, and first released on February 20, 1991.
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. It is also used to create various machine learning algorithm, and helps in Artificial Intelligence. Python is a general purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today. A survey conducted by industry analyst firm RedMonk found that it was the most popular programming language among developers in 2020.

Problem:
Basic mathematical functions operate element-wise on arrays. They are available both as operator overloads and as functions in the NumPy module.
import numpy a = numpy.array([1,2,3,4], float) b = numpy.array([5,6,7,8], float) print a + b #[ 6. 8. 10. 12.] print numpy.add(a, b) #[ 6. 8. 10. 12.] print a - b #[-4. -4. -4. -4.] print numpy.subtract(a, b) #[-4. -4. -4. -4.] print a * b #[ 5. 12. 21. 32.] print numpy.multiply(a, b) #[ 5. 12. 21. 32.] print a / b #[ 0.2 0.33333333 0.42857143 0.5 ] print numpy.divide(a, b) #[ 0.2 0.33333333 0.42857143 0.5 ] print a % b #[ 1. 2. 3. 4.] print numpy.mod(a, b) #[ 1. 2. 3. 4.] print a**b #[ 1.00000000e+00 6.40000000e+01 2.18700000e+03 6.55360000e+04] print numpy.power(a, b) #[ 1.00000000e+00 6.40000000e+01 2.18700000e+03 6.55360000e+04]
Task :
You are given two integer arrays, A and B of dimensions NXM.
Your task is to perform the following operations:
- Add ( A + B)
- Subtract ( A – B)
- Multiply ( A * B)
- Integer Division (A / B)
- Mod (A % B)
- Power (A ** B)
Input Format :
The first line contains two space separated integers, N and M.
The next N lines contains M space separated integers of array A.
The following N lines contains M space separated integers of array B.
Output Format :
Print the result of each operation in the given order under Task.
Sample Input :
1 4 1 2 3 4 5 6 7 8
Sample Output :
[[ 6 8 10 12]] [[-4 -4 -4 -4]] [[ 5 12 21 32]] [[0 0 0 0]] [[1 2 3 4]] [[ 1 64 2187 65536]]
