# Inner and Outer in Python – HackerRank Solution

innerThe inner tool returns the inner product of two arrays.

```import numpy

A = numpy.array([0, 1])
B = numpy.array([3, 4])

print numpy.inner(A, B)     #Output : 4
```

outer The outer tool returns the outer product of two arrays.

```import numpy

A = numpy.array([0, 1])
B = numpy.array([3, 4])

print numpy.outer(A, B)     #Output : [[0 0]
#          [3 4]]
```

You are given two arrays: A and B.

#### Input Format :

The first line contains the space separated elements of array A.
The second line contains the space separated elements of array B.

#### Output Format :

First, print the inner product.
Second, print the outer product.

```0 1
2 3
```

```3
[[0 0]
[2 3]]```
