Explanation of Solution
Differences between method overloading and overriding:
| Overloading a method | Overriding a method |
| Methods have the same name with different parameters. | Methods have the same name with same parameters of superclass in the subclass. |
| Reusability can be achieved. | No reusability. |
| It blocks the inheritance from super class... |

I need help finishing my python rock paper scissors code, where it asks the user "rock, paper, scissors", the user types either option (repeatedly asks until its one of the three), and for a random option from the code to select also rock paper scissors. The end result would be you winning, code winning, or a tie.My code:import randomOPTIONS = ("ROCK", "PAPER", "SCISSOR")
def getInput(): """ Function getInput() will receive and validate user input to be the string ROCK, PAPER, or SCISSOR. Input must be spelled correctly and in all capital letters. Function will return the validated input
@return user input as ROCK, PAPER, OR SCISSOR """ #need help here

I need help understanding how could I got the IP Address for the 1st Host on this Subnet, the IP Address for the Last Host on this Subnet & the Broadcast Address for this Subnet
My Explanation:8 bits --> 17 & 0
128 64 32 16 | 8 4 2 1 0 0 0 1 0 0 0 1 -->17+ 0 0 0 0 0 0 0 0 --> 0 0 0 0 0 0 0 0 0 --> 0 (The Major (Base) Network Address): 142.20.33.0
To find the broadcast address, we can set all the bits in the host portion of the address to 1, which gives us 142.20.33.255. Based on the subnet mask 255.255.255.0, no bits were borrowed from the host portion, meaning 8 bits remain in the host portion. Using the formula 2^h – 2 (where h represents the number of host bits), we get 2^8 - 2 = 254 hosts.
8 bits --> 17 & 252

- Objective you will: 1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five) 2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector. 3. Compare the performance of TreeSort with C++'s std::sort on large datasets. Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST): 1. Insert all elements into a BST (logically sorting them). 2. Traverse the BST in-order to extract elements in sorted order. 3. Store the sorted elements in a vector.
