AI Summary: A user submitted a contact form requesting an official solution for the "CSES - Minimal Grid Path" problem. They noted that this specific problem is missing a solution on the USACO Guide page for 'Gold - Paths on Grids'.

AI Summary: A user submitted a contact form request reporting that the 'week 2 class video recording' link on usaco.guide points to a blank 7-minute video. They are requesting this be fixed so they can catch up on the class material.

AI Summary: This GitHub issue is a suggestion from a contact form submission regarding the third C++ solution for the 'CSES - Graph Girth' problem. The user requests the removal of macros from this specific solution, citing that they make the code messy and harder to read.

AI Summary: A user reported via the contact form that the solution example for the "2025 January Contest, Bronze Cow Checkups" module on USACO Guide is incorrect. They provided an example of the wrong output (`6, 0, 0, 0`) that results from using the current solution example. This issue is labeled as a "good first issue" and relates to content.

AI Summary: A user reported a broken link on the "Gold - Introduction to DP" module, specifically under the "RESOURCES -> CF -> Beginner DP Contest" section. The provided URL is malformed, embedding the Codeforces link within the hash of the usaco.guide page, causing it to be inaccessible. The issue requires correcting this link to the intended Codeforces blog post.

AI Summary: This GitHub issue reports a potential mistake in the provided solution for the USACO Bronze 2022 US Open - Photoshoot problem. The user submitted a contact form, stating that the current solution outputs 2 flips for a specific test case ("H H H G G H H G H G"), while they believe the correct minimum number of flips should be 3. They are seeking clarification on whether they might be misunderstanding a problem detail.

AI Summary: The task is to correct a mistake in a C++ code snippet related to prefix sums. The code calculates the sum of elements within a given range using prefix sums, but it has an off-by-one error in the index. The correction involves adjusting the subtraction to use `p[r] - p[l-1]` instead of `p[r] - p[l]` to accurately reflect the sum of elements in the specified range.

AI Summary: The task involves processing a contact form submission from the USACO Guide website. Specifically, the issue highlights a submission related to the 'Silver - Additional Practice for USACO Silver' module, pointing to a potential error in the 'Mistake' topic concerning the '2013 - Dreaming' problem. The required action is likely to investigate and address the reported issue, potentially updating the relevant section of the website.

AI Summary: The task is to address a reported issue concerning an incorrect time complexity in a solution provided within the USACO Guide's Divisibility module (Gold section). The issue points out that the current solution for the GCD Extreme problem from SPOJ is too slow (O(N) per query) and suggests a more efficient O(N logN) preprocessing solution. The required action is to investigate the claim, verify the time complexity, and potentially update the guide with a corrected or improved solution.

AI Summary: Address a user's feedback on a lengthy solution to a competitive programming problem ('CF - Books') within the USACO Guide. The feedback suggests the solution is overly complex and requests a simpler alternative or a review of the existing solution for potential improvements.

AI Summary: The task is to review a suggestion submitted through a contact form on the USACO Guide website. The suggestion proposes adding merge sort trees to the 'More Applications of Segment Tree' module, as they are not currently covered and are considered a relevant extension of segment tree concepts.

AI Summary: Improve the "Bronze - Introduction to Graphs" section of the USACO Guide website. The task involves enhancing the existing content to provide clearer explanations, potentially adding a section on graph coloring, and improving the clarity and explanations of existing solutions to make them easier for users to understand.

AI Summary: Investigate a contact form submission reporting an incorrect class time and an inaccessible webpage for the Mandarin module. The issue points to a problem with the 'usaco.guide/dashboard' page's Mandarin content.

AI Summary: The task is to address a user's inquiry regarding the inclusion of Topcoder problems in the USACO Guide's Gold - Knapsack DP module. The user suggests removing Topcoder problems if there's no mechanism for submission, implying a potential inaccuracy or outdated link within the guide.

AI Summary: The task is to address a user's suggestion regarding the order of problems in the "Silver - More on Prefix Sums" section of the USACO Guide. The user suggests rearranging problems to ensure that prerequisite concepts (like difference arrays) are covered before problems requiring them are presented.

AI Summary: Investigate and resolve an error encountered by a user attempting to join a group via a unique link provided in a contact form submission. The error message is "Error: INTERNAL". The user has already attempted to contact support via email, but the email bounced. The task involves debugging the group joining process and potentially contacting the appropriate technical team to resolve the issue.

AI Summary: The task is to address a user's confusion regarding joining a group after submitting a contact form on the USACO Guide website. The user received a message indicating they need a join link from a club officer or instructor, but their email to the provided address bounced back. The required action is to investigate the issue, potentially update the website's messaging for clarity, and/or provide the user with the correct procedure for joining.

AI Summary: The task is to investigate a reported error in the 'Silver - More on Prefix Sums (Max Subarray Sum Solution)' module of the USACO Guide. The reported error concerns the formula used to calculate subarray sums, specifically its handling of negative numbers. The task involves verifying the claim, determining if it's a genuine error, and providing a correction or explanation if necessary.
