Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Use python and do not use any library. Remove the pass line and complete the code after #todo section

class CircularArray:
definit_(self, lin, st, sz):
Variables
# Initializing
self.start=0
self.size = 0
self.cir = []
# if lin = [10, 20, 30, 40, None]
# then, CircularArray (lin, 2, 4) will generate
#cir = [40, null, 10, 20, 30]
# To Do.
# Hints: set the values for initialized variables
# Print from index to len(cir) - 1
def printFullLinear(self): #Easy
# To Do
pass # Remove this line
# Print from start index and total size elements
def printForward(self): #Easy
# To Do
pass # Remove this line
def printBackward(self): #Easy
# To Do
pass # Remove this line
# Tester class. Run this cell after completing methods in the upper cell and
#check the output
lin_arr1 = [10, 20, 30, 40, None]
print("==========Test 1==========")
|c1 = CircularArray (lin_arr1, 2, 4)
c1.printFullLinear() # This should print: 40, None, 10, 20, 30
c1.printForward() # This should print: 10, 20, 30, 40

Python please Use map(s) to program this formula: Σ [ (xi – x)(yi – y) ] / Σ [ (xi – x)^2] Note the Σ symbol means "SUM" where the sum goes from 0 to a limit. And the ^2 at the end of the equation means 'squared'.
