Explanation of Solution
Web Content Accessibility Guidelines (WCAG):
The guidelines for web accessing have been developed through the W3C process. The purpose of these guidelines is to provide the accessibility of web contents like text, images, structure, presentation, and so on.
Usage of color and images that was mentioned in “WCAG 2.0”:
Color element is to conveying the information interactively. All web elements use color for their text, background, or other styling purpose. The sufficient techniques are as follows:
- Ensuring the color in data, backgrounds, or other contents is to indicate the information.
- Ensuring the color within an image to convey the information.
- Images are used to provide picture in the web page. The user can modify the properties like border, size, and alternative text for an image.
Web page:
The following code is used to demonstrate “WCAG” with color and image element:
Code:

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")

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
128 64 32 16 | 8 4 2 1 0 0 0 1 0 0 0 1 --> 17+ 1 1 1 1 1 1 0 0 --> 252 0 0 0 1…

- 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.
