Write a program that uses a function called findinlist() to check for the position of the first occurrence of v in the list passed as parameter (lst) or -1 if not found. The header for the function is given below :

def find_in_list(lst, v):
""" lst - a list
v - a value that may or
may not be in the list """

Implement the following function for a linear list, which find outs and returns the number of unique elements in the list

def unique(lst):
"""passed parameter lst is a list of 
integers (could be empty)."""

After implementing the above function, test it with following lists and show the output produced by above function along with the reason for that output.

(i) lst = []

(ii) lst = [1, 2, 3]

(iii) lst = [1, 2, 2]

(iv) lst = [1, 2, 2, 3, 3]

Take two lists, say for example these two :

a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

and write a program that returns a list that contains only the elements that are common between the lists (without duplicates). Make sure your program works on two lists of different sizes. Write this in one line of Python using at least one list comprehension. Run the complete program and show output.

Suppose we have a list V where each element represents the visit dates for a particular patient in the last month. We want to calculate the highest number of visits made by any patient. Write a function MVisit(Lst) to do this.

A sample list (V) is shown below :

V = [[2, 6], [3, 10], [15], [23], [1, 8, 15, 22, 29], [14]]

For the above given list V, the function MVisit() should return the result as [1, 8, 15, 22, 29].
