Greedy Algorithms - Partition Labels
Given the same code as above, what is the output when the input string is a single character "z"?
Given the same code as above, what is the output when the input string is a single character "z"?
medium🧾 Code Trace Q4 of Q15
Step-by-Step Solution
Solution:
Step 1: Last occurrence for 'z'
Index is 0 since only one character.Step 2: Partition formed at index 0
Partition length is end - start + 1 = 0 - 0 + 1 = 1.Final Answer:
Option D -> Option DQuick Check:
Single character string forms one partition of length 1 [OK]
Quick Trick: Single char string -> one partition length 1 [OK]
Common Mistakes:
MISTAKES- Returning empty list for single char
- Miscomputing partition length
Trap Explanation:
PITFALL- Some candidates forget to handle single character edge case correctly.
Interviewer Note:
CONTEXT- Tests boundary condition handling in code trace.
