## NumPy: Array Object Exercise-166 with Solution

Write a NumPy program to combine last element with first element of two given ndarray with different shapes.

Sample Solution:

Python Code:

``````import numpy as np
array1 = ['PHP','JS','C++']
array2 = ['Python','C#', 'NumPy']
print("Original arrays:")
print(array1)
print(array2)
result  = np.r_[array1[:-1], [array1[-1]+array2], array2[1:]]
print("\nAfter Combining:")
print(result)
```
```

Sample Output:

```Original arrays:
['PHP', 'JS', 'C++']
['Python', 'C#', 'NumPy']

After Combining:
['PHP' 'JS' 'C++Python' 'C#' 'NumPy']
```
