このあたりの整え方を見ておいてください。
あ、私のしているコメントを GPT に放り込んでどう思うかなどを聞くのもいいです。

一旦自分の中でどうすれば解けるかをまとめてから、それをコードでどう表現するかという流れで問題に取り組むと、最初から動くコードが書けるかなと感じます。
これも読むと参考になると思います！

問題文の概要
Given the head of a linked list, return the node where the cycle begins. If there is no cycle, return null.
There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following the next pointer. Internally, pos is used to denote the index of the node that tail's next pointer is connected to (0-indexed). It is -1 if there is no cycle. Note that pos is not passed as a parameter.
Do not modify the linked list.
