Complex Multi-Rule Hard
Complex Multi-Rule problems combine multiple sorting and transformation rules applied sequentially. Common patterns include sorting words by length, sorting numbers numerically, then interleaving them in a specific pattern. These problems test advanced sequential reasoning and multi-rule application skills.

Introduction to Complex Multi-Rule Hard
Complex Multi-Rule problems combine multiple sorting and transformation rules applied sequentially. Common patterns include sorting words by length, sorting numbers numerically, then interleaving them in a specific pattern. These problems test advanced sequential reasoning and multi-rule application skills.
Prerequisites
How to Solve Complex Multi-Rule Hard Problems
Step 1: Separate words and numbers from the input
Step 2: Apply the first rule (e.g., sort words by length)
Step 3: Apply the second rule (e.g., sort numbers in ascending order)
Step 4: Apply the third rule (e.g., interleave in a specific pattern)
Step 5: Track intermediate results after each rule application
Step 6: The final output is the result after all rules are applied
Step 7: Verify all rules were applied correctly
Example Problem
Example: Input: 'sun 45 moon 23 star 78' Rule 1: Sort words by length Rule 2: Sort numbers ascending Rule 3: Alternate (word, number) Step 1: Words: 'sun'(3), 'moon'(4), 'star'(4) → sorted by length: 'sun', 'moon', 'star' (moon and star both length 4, then alphabetically) Step 2: Numbers: 45,23,78 → sorted: 23,45,78 Step 3: Alternate: 'sun 23 moon 45 star 78' Answer: sun 23 moon 45 star 78
Pro Tips & Tricks
- Apply rules sequentially, not simultaneously
- Write intermediate results after each step to avoid confusion
- For word sorting by length, then alphabetically: use key=lambda x: (len(x), x)
- For number sorting: use key=int or default numeric sorting
- For interleaving, identify which group starts the pattern
- If lists have different lengths, extra items go at the end
