The first line of input contains an integer n, representing the number of elements in the given array. 

The second line of input contains n space separated integers, representing elements of the given array. 

2

25 10 


Expected Output 

Print the last two digits of the product of array values. 

Note that you always need to print two digits.


Constraints 

1<=n<=100

1<=ar[i]

ar[i] is the element of the array  

                ### YOUR TASK ###
                def output(arr):
                    ### Write you code logic here ###
                    
                    product_arr = 1
                    for i in arr:
                        product_arr*=i 
                    print("Product of array:",product_arr)
                    product_arr_str=str(product_arr)
                    return product_arr_str[-2:]
                
                # XOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOX #
                
                ### ALREADY GIVEN PROGRAM: ###
                
                # Product of given integer array elements 
                # print only last 2 digits of the product
                def convert_int(arr):
                    new_arr = []
                    for item in arr:
                        new_arr.append(int(item))
                    return new_arr
                
                # Input array
                InputArray = []
                n = int(input("Enter the number of elements:"))
                print(n)
                length = 0
                while True:  
                    InputArray = input("Enter Array with n spaces : ").split(' ')
                    print(len(InputArray))
                    if len(InputArray) == n:
                        break
                    else:
                    	print('Invalid , check the number of elements.' )
                        
                InputArray = convert_int(InputArray)
                
                # Call the function output passing InputArray
                print("last two digits of product array : ", output(InputArray))

Output :

Execution of the above program will be accepting the three numbers if not it will ask again for input..

As per the logic required to be product of 3 members will be displayed and last digits of the product will be displayed.

Python Sets and Dictionaries

By
Python Sets Python Maps examples A mapping object maps hashable values to arbitrary objects. Mappings are mutable objects. There is currently only one standard mapping type, the dictionary. Dictionaries consist of pairs (called items) of keys and their corresponding values. Dictionaries can be created by placing a comma-separated list of key: value pairs within curly braces Keys are unique within a dictionary while values may not be. The values of a dictionary can be of any type, but the keys must be of an immutable data type such as strings, numbers, or tuples. Python Set Operations and methods Python Set methods continueed >>> SET={'new','old','list','new'} >>> SET set(['new', 'old', 'list']) Lets play with set operations, it is more like school math here... >>> s={1,2,3,4} >>> k={3,4,5,6} >>> len(s) 4 >>> len(k) 4 >>> 1 in s True >>...

Program Controls and loops in Python

By
Python Programming controls The flow of program will be controlled with conditional statements where this flow  if condition if-else condition if-elif condition while loop while - else loop for loop for with if- else loop if condition Here I would like to work on program control statements, wherein relate some operating system functionalities so that, this would give some basic prototype for the sys admin scripts. #!/usr/bin/python # This illustrate if condition # Filename : ifex.py import os d=os.listdir('/home/pavanbsd/pybin') print d f='ifex.py' if f in d: print "File exists" else: print "Not found..." if-elif-else ladder No worries, coming soon... When you need the task that need to be done repeatedly then your choice is using loops. Python provides two simple loop constructs easy to use! More powerful then other scripting compare to, it has 'else' block. while loop Understand the power of while loop,...
