Decomposition 分层思维

Decomposition is the process of breaking large problems into smaller parts. These smaller parts are easier to understand, making the problem easier to solve.

分层思维是将一个大问题拆解成许多小的部分。这些小部分更容易理解，让问题更加容易解决。

Pattern Recognition 模式识别

Pattern recognition is the process of identifying patterns and trends among the parts of a problem. You can find patterns from previous experiences and apply them to other problems as well!

模式识别是识别不同问题中的模式和趋势（共同点）的过程。你能从以往的经验中得到规律并且举一反三将它运用到其他的问题中。

Sequential patterns are when you arrange items in sequence:

Grouping patterns are when you group items that are similar:

分组模式是将相似的项目(物品)分成一个组

If you guessed them correctly, that’s abstraction! You have focused on their defining features.

如果你猜对了，那你就知道什么是抽象化了。你要关注它们最典型的特征。
