Analysis of Mistakes

Overall, the mistakes highlight a need to focus on understanding data scope, applying logic to programming rules, and interpreting algorithm performance.

Key Issues:

• In the first question, the error came from underestimating the inferences possible from the given data. Practice analyzing datasets for all potential calculations.
• The second question highlighted a misunderstanding of replacement rules. Improve programming logic, particularly with conditions and calculations.
• The third question revealed a gap in understanding time complexity; polynomial growth was incorrectly judged as unreasonable.

Key Screenshots

Why I Got These Questions Wrong

I made these mistakes mainly because I didn't take enough time to reread the questions and focus on the key details. In some cases, I overlooked specific instructions or misunderstood what was being asked, especially when it came to identifying key terms or conditions. I also sometimes rushed through programming logic or assumptions, which led to incorrect conclusions. To improve, I plan to take extra care in reading each question carefully, paying close attention to the small but important details, and avoiding assumptions based on incomplete information.

Sprint 3 code snippet

/**
 * Fetch posts based on selected channel
 * Handle response: Fetch and display posts
 */
async function fetchData(channelId) {
    try {
        const response = await fetch(`${pythonURI}/api/posts/filter`, {
            ...fetchOptions,
            method: 'POST',
            headers: {
                'Content-Type': 'application/json'
            },
            body: JSON.stringify({ channel_id: channelId })
        });
        if (!response.ok) {
            throw new Error('Failed to fetch posts: ' + response.statusText);
        }

        // Parse the JSON data
        const postData = await response.json();

        // Extract posts count
        const postCount = postData.length || 0;

        // Update the HTML elements with the data
        document.getElementById('count').innerHTML = `<h2>Count ${postCount}</h2>`;

        // Get the details div
        const detailsDiv = document.getElementById('details');
        detailsDiv.innerHTML = ''; // Clear previous posts

        // Iterate over the postData and create HTML elements for each item
        postData.forEach(postItem => {
            const postElement = document.createElement('div');
            postElement.className = 'post-item';
            postElement.innerHTML = `
                <h3>${postItem.title}</h3>
                <p><strong>Channel:</strong> ${postItem.channel_name}</p>
                <p><strong>User:</strong> ${postItem.user_name}</p>
                <p>${postItem.comment}</p>
            `;
            detailsDiv.appendChild(postElement);
        });

    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

// Fetch groups when the page loads
fetchGroups(); </script>

Explanation of Code

• The function fetchData(channelId) retrieves posts associated with a specific channel using the channel's ID.
• It sends an asynchronous POST request to the API endpoint with the channel ID in the request body.
• After receiving a response, it checks if the request was successful; if not, it throws an error.
• The JSON data from the response is parsed, and the total count of posts is extracted and displayed on the page.
• It clears the previous content in the "details" section and dynamically creates new elements for each post, displaying the post title, channel name, user, and comment.
• Errors during the fetch process are caught and logged in the console for debugging purposes.
