Assignment-7
						============
1. Write a python function that returns the index of the smallest element in a list of 
integers. If the number of such elements is greater than 1, return the smallest index. 
Use the following function header:
def indexOfSmallestElement(lst):

Ans:-
=====

def indexOfSmallestElement(lst):
    smallValue = min(lst)
    return lst.index(smallValue)
    
lst = [20,10,30,10,50,40,10]
smallIndex = indexOfSmallestElement(lst)
print(smallIndex);

Output:-
========

1

==================================================================================================
2. Write the python function mostCommonName, that takes a list of names (such as ["Ja
ne", "Aaron", "Cindy", "Aaron"], and returns the most common name in this list 
(in this case, "Aaron"). If there is more than one such name, return a set of the most 
common names. So mostCommonName(["Jane", "Aaron", "Jane", "Cindy", "Aaron"])
returns the set {"Aaron", "Jane"}. If the set is empty, return None. Also, treat names
case sensitive, so "Jane" and "JANE" are different names.

Ans:-
=====

def mostCommonName(lst):
    dict_of_counts = {item:lst.count(item) for item in lst}
    max_frequent_val = max(dict_of_counts.values())
    res = {key for key in dict_of_counts if dict_of_counts[key] == max_frequent_val}
    return res
    
lst = ["Jane", "Aaron", "Jane", "Cindy", "Aaron"]
mostCommonList = mostCommonName(lst);
print(mostCommonList)

Output:-
========
   
{'Jane', 'Aaron'}

=============================================================================================

3. Write the python function isPalindromicList(a) that takes a list and returns True if it is
the same forwards as backwards and False otherwise.

Ans:-
=====

def isPalindromicList(strVal):
   if strVal == strVal[::-1]:
      print("The list is a palindrome")
   else:
      print("The list isn't a palindrome")

lst = [77, 1, 56, 65, 1, 77]

print("The list is :")
print(lst)

my_list = ' '.join([str(elem) for elem in lst])
isPalindromicList(my_list)

Output:-
========
   
The list is :
[77, 1, 56, 65, 1, 77]
The list is a palindrome
