Straight Traversal
Straight Traversal is a algorithm in the linked lists family. This linked-list algorithm walks references rather than indexed positions, so pointer/reference order is the main source of correctness.

불필요한 전문용어 없이 동작 방식 이해하기
Straight Traversal should be understood through its invariant and the state it changes at each step.
The practical complexity in this reading is Varies by implementation / input constraints; always connect that cost to the actual loops, recursion, data structure operations or input assumptions.
알고리즘을 연속된 의사결정으로 읽기
Save the next node before rewiring when needed.
Advance current/previous pointers carefully.
Handle empty list and one-node list.
Read a tiny input by hand and write down the state after every important operation. For Straight Traversal, the goal is to make the invariant visible rather than to memorize code.
Varies by implementation / input constraints
Do not quote this complexity mechanically. Ask which operation or input dimension it describes, then derive the cost from the loops, recursion depth, data-structure operations and any preprocessing assumptions.
적합한 경우
- Useful when the problem is defined directly on node links.
보통 어디에서 문제가 생기는가
- Losing the rest of the list after overwriting next.
- Null-reference edge cases.

A strong interview explanation of Straight Traversal should cover the problem it solves, its invariant, the important data structure/state, its Varies by implementation / input constraints cost, and the constraint that would make you choose a different approach.
What problem does Straight Traversal solve?
Straight Traversal is a algorithm in the linked lists family. This linked-list algorithm walks references rather than indexed positions, so pointer/reference order is the main source of correctness.
복잡도에 대해 무엇을 언급해야 하나요?
Its typical cost here is Varies by implementation / input constraints, but a complete answer should connect that cost to the representation, input constraints and the dominant operations.
가장 흔한 실수는 무엇인가요?
Losing the rest of the list after overwriting next.
