Answer:
3) A Single linked list is a sequence of elements in which every element has link to its next element in the sequence.
DATA LINK
DATA stores actual value , LINK stores address of next node
As per information given in question, letters at the even addresses are items in linked list and the odd addresses will be used as links.
Even Address Odd Address
12 (Stores 't') 13 (Used as link)
14 (Stores 'm') 15 (Used as link)
16 (Stores 'a') 17 (Used as link)
18 (Stores 'r') 19 (Used as link)
20 (Stores 's') 21 (Used as link)
Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.
Following image represents the word "smart" with respective nodes and their addressing.
Numbers represented by circle are addresses of respective nodes.
The head pointer is: 20
Answer:
The solution code is written in Python:
- COST_PER_500MI = 1.1
-
- weight = float(input("Enter weight of package: "))
- total_cost = weight * COST_PER_500MI
- print("The shipping charges is $" + str(round(total_cost,2)))
Explanation:
Based on the information given in the question, we presume the cost per 500 miles is $1.10 per pound ($2.20 / 2 pound).
Create a variable COST_PER_500MI to hold the value of cost per 500 miles (Line 1). Next, prompt user input the weight and assign it to variable weight (Line 3). Calculate the shipping charge and display it using print function (Line 4-5).
Answer:
