hard🔁 Follow Up Q10 of Q15
Step-by-Step Solution
Solution:
Step 1: Recognize uniqueness constraint
Parts must be distinct, so standard integer break DP needs modification.Step 2: Use DP with subset constraints
Track which integers are used to ensure uniqueness, similar to subset sum problems.Final Answer:
Option A -> Option AQuick Check:
Uniqueness requires state tracking in DP [OK]
Quick Trick: Uniqueness needs DP with extra state tracking [OK]
Common Mistakes:
MISTAKES- Using greedy which ignores uniqueness
- Ignoring memoization leading to exponential time
- Applying BFS without pruning causes inefficiency
Trap Explanation:
PITFALL- Greedy ignores uniqueness, causing incorrect solutions
Interviewer Note:
CONTEXT- Tests ability to adapt DP to additional constraints
