# Arrays python

### Problem Statement :

```The NumPy (Numeric Python) package helps us manipulate large arrays and matrices of numeric data.

To use the NumPy module, we need to import it using:

import numpy
Arrays

A NumPy array is a grid of values. They are similar to lists, except that every element of an array must be the same type.

import numpy

a = numpy.array([1,2,3,4,5])
print a[1]          #2

b = numpy.array([1,2,3,4,5],float)
print b[1]          #2.0
In the above example, numpy.array() is used to convert a list into a NumPy array. The second argument (float) can be used to set the type of array elements.

You are given a space separated list of numbers.
Your task is to print a reversed NumPy array with the element type float.

Input Format

A single line of input containing space separated numbers.

Output Format

Print the reverse NumPy array with type float.```

### Solution :

```                            ```Solution in C :

import numpy

def arrays(arr):
# complete this function
# use numpy.array
arr.reverse()
numpy_arr = numpy.array(arr,float)
return numpy_arr

arr = input().strip().split(' ')
result = arrays(arr)
print(result)```
```

## Delete a Node

Delete the node at a given position in a linked list and return a reference to the head node. The head is at position 0. The list may be empty after you delete the node. In that case, return a null value. Example: list=0->1->2->3 position=2 After removing the node at position 2, list'= 0->1->-3. Function Description: Complete the deleteNode function in the editor below. deleteNo

## Print in Reverse

Given a pointer to the head of a singly-linked list, print each data value from the reversed list. If the given list is empty, do not print anything. Example head* refers to the linked list with data values 1->2->3->Null Print the following: 3 2 1 Function Description: Complete the reversePrint function in the editor below. reversePrint has the following parameters: Sing

Given the pointer to the head node of a linked list, change the next pointers of the nodes so that their order is reversed. The head pointer given may be null meaning that the initial list is empty. Example: head references the list 1->2->3->Null. Manipulate the next pointers of each node in place and return head, now referencing the head of the list 3->2->1->Null. Function Descriptio
