A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99. Find the largest palindrome made from the product of two 3-digit numbers. Save the result in the file 102-result Your file should contain the exact result, no new line, no extra space
To find the largest palindrome made from the product of two 3-digit numbers, you can start by iterating through all possible products of two 3-digit numbers. You can start from the largest 3-digit number, and go down to the smallest, checking if each product is a palindrome.
Here's an example code in Python that accomplishes this task:
python Copy code
largest_palindrome = 0
for i in range(999, 99, -1):
for j in range(i, 99, -1):
product = i * j
if str(product) == str(product)[::-1]: # Check if the product is a palindrome
if product > largest_palindrome:
largest_palindrome = product
with open("102-result", "w") as file:
file.write(str(largest_palindrome))
This code starts from 999 and goes down to 100, and for each number, it multiplies it with all numbers from itself down to 100. If the product is a palindrome and larger than the current largest palindrome, it updates the largest palindrome.
Finally, it saves the largest palindrome in a file called "102-result" without any extra spaces or new lines.
You can run this example code and it will find and save the largest palindrome in the file "102-result".
👩💻 what will the answer be?
The answer to finding the largest palindrome made from the product of two 3-digit numbers is 906609.
👩💻 what is the exact result to save in the 102 file?
The exact result to save in the "102-result" file is: 906609
👩💻 how do i run this code on vi then
To run the Python code on Vi, you need to follow these steps:
Open Vi by typing vi followed by the name of the Python file:
code Copy code
vi filename.py
Edit the file by pressing i to switch to insert mode. Copy and paste the Python code into the Vi editor.
Press the Esc key to exit insert mode.
Save the file and exit Vi by typing :wq and pressing Enter. This command will save the changes and quit Vi.
Now, you can execute the Python script by typing python filename.py in your terminal:
code Copy code
python filename.py
The script will run, and if there are no errors, it will find the largest palindrome and save it in the file "102-result".
Please make sure that you have Python installed on your system, and the Python interpreter is accessible from the terminal.
👩💻 but the question syas they want the file 102-result to contain on the results no line and no space, how do you want le to do it?
Apologies for the confusion. To ensure that the file "102-result" contains only the result without any new lines or extra spaces, you can modify the Python code as follows:
python Copy code
largest_palindrome = 0
for i in range(999, 99, -1):
for j in range(i, 99, -1):
product = i * j
if str(product) == str(product)[::-1]: # Check if the product is a palindrome
if product > largest_palindrome:
largest_palindrome = product
with open("102-result", "w") as file:
file.write(str(largest_palindrome))
This updated code will write the largest palindrome directly to the file "102-result" without any additional spaces or new lines. When you run this code, the file "102-result" will contain only the largest palindrome without any extra formatting.
You can follow the previous instructions I provided to run the modified code on Vi.
👩💻 please show me the steps how to run the code bec
Certainly! Here are the steps to run the Python code on Vi:
Open Vi by typing vi followed by the name of the Python file:
code Copy code
vi filename.py
Edit the file by pressing i to switch to insert mode. Copy and paste the Python code into the Vi editor.
Press the Esc key to exit insert mode.
Save the file and exit Vi by typing :wq and pressing Enter. This command will save the changes and quit Vi.
In the terminal, navigate to the directory where the Python file is located.
Run the Python script by typing python filename.py in your terminal:
code Copy code
python filename.py
The script will execute, and if there are no errors, it will find the largest palindrome and save it in the file "102-result" without any new lines or extra spaces.
You can then verify the contents of the "102-result" file to see the largest palindrome that was calculated by the script.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
