Question

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, and of dimensions X.
Your task is to perform the following operations:

Add ( + )
Subtract ( - )
Multiply ( * )
Integer Division ( / )
Mod ( % )
Power ( ** )

Note
There is a method numpy.floor_divide() that works like numpy.divide() except it performs a floor division.

Input Format

The first line contains two space separated integers,  and .
The next  lines contains  space separated integers of array .
The following  lines contains  space separated integers of array .

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]]

Use // for division in Python 3.
