Q.1 Write a function called range_roller( ) that takes in two parameters N and K, both as integers. The function should do the following using the range( ) function:

-Return a list of numbers from N to 2N+1 (maximum must not be greater than 2N+1) with step size=3, if and only if K=0

-Return a list of numbers from N to 0 (minimum must not be lesser than 0) with step size=2, if and only if K=1

-Return -1 if K is neither 0 nor 1

Two examples are shown below:

Input: (9, 0)

Output: [9, 12, 15, 18]

Input: (11, 1)

Output: [11, 9, 7, 5, 3, 1]

Q.2 Write a function called while_it( ) that takes in no parameters and returns a list of the series, 105,98,91,,7.

Constraint: You have to use a while loop to implement this

Q.3 Write a function called num_sum( ) that takes in an integer N as a parameter and computes the sum of digits of N using a while loop. The function should return the computed sum. Two examples are shown below:

Input: (984)

Output: 21

Input: (21)

Output: 3

Q4. Write a function called greatest_integer( ) that takes in three parameters (A,B,C) and uses logical operators to determine the largest and the smallest number among these three. The function should return the largest and the smallest number in the form of a list which is supposed to be arranged in descending order. Two examples are shown below:

Input: (100, 3, 1)

Output: [100, 1]

Input: (3, 4, 4)

Output: [4, 3]

Q5. Write a function called square_pair( ) that takes in two lists, namely first list and the second list as parameters. The first list would contain a series of integers and the second list would contain the squares of the integers in the first list, at corresponding indexes. The task is to construct and return a list, containing all corresponding pairs of integers and their squares positioned adjacently. Also entries in every pair should be visible in ascending order. Furthermore your function should return -1 if the two input lists are of distinct lengths. Two examples are shown below:

Input: ([1, 4, 2],[1, 16, 4])

Output: [1, 1, 4, 16, 2, 4]

Input: ([3, 5, 1],[9, 25] )

Output: -1
