Greedy Algorithms - Maximum Units on a Truck
You have a truck with limited capacity and multiple box types, each with a count and units per box. Which algorithmic pattern best fits maximizing total units loaded?
You have a truck with limited capacity and multiple box types, each with a count and units per box. Which algorithmic pattern best fits maximizing total units loaded?
easy🔍 Pattern Recognition Q1 of Q15
Step-by-Step Solution
Solution:
Step 1: Identify problem constraints
The problem allows picking whole boxes up to truck capacity, aiming to maximize units.Step 2: Recognize greedy choice property
Choosing boxes with highest units per box first leads to optimal total units without needing exhaustive search.Final Answer:
Option A -> Option AQuick Check:
Greedy sorting by units per box is optimal for this problem [OK]
Quick Trick: Maximize units by picking highest units per box first [OK]
Common Mistakes:
MISTAKES- Thinking DP is needed because of capacity constraint
Trap Explanation:
PITFALL- Candidates often confuse this with knapsack needing DP, but greedy suffices here.
Interviewer Note:
CONTEXT- Tests candidate's ability to recognize greedy pattern applicability.
