25 10 

Expected Output 

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

Note that you always need to print two digits.

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:]

                ### 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.
