What It Looks Like
Recognition signals — when you see these, think of this structure:
- 1From A to B, find shortest
- 2Several possible paths
- 3Distance or length comparison
🎯
What It Really Tests
The core mathematical idea behind this structure:
The shortest route should be compared structurally, not guessed visually.
最短路径应该通过结构比较来确定, 而不是凭直觉猜。
⚠️
Why Students Get Stuck
Common mistakes to watch out for:
- ⚠Choosing what looks shorter without measuring
- ⚠Not checking all valid routes
- ⚠Missing a hidden shortcut
💡
Your First Step
How to begin thinking about problems with this structure:
List all candidate routes and compare their lengths systematically.
列出所有候选路径, 系统地比较它们的长度。
