Greedy Algorithms - Assign Cookies

You have two arrays: one representing children's greed factors and another representing cookie sizes. You want to maximize the number of children who get a cookie that satisfies their greed. Which algorithmic pattern best fits this problem?

AGreedy algorithm with sorting and two pointers to assign cookies

BDivide and Conquer by splitting children and cookies into halves

CBacktracking to try all cookie assignments for maximum satisfaction

DDynamic Programming with state transitions based on greed and cookie sizes

Step-by-Step Solution

Solution:

Step 1: Identify problem constraints
The problem requires maximizing assignments where each cookie can be assigned at most once, and greed factors must be satisfied.
Step 2: Match pattern to algorithm
Greedy sorting and two pointers efficiently assign smallest sufficient cookie to each child, maximizing count.
Final Answer:
Option A -> Option A
Quick Check:
Greedy sorting matches problem constraints perfectly [OK]

Quick Trick: Maximize assignments with sorted greedy matching [OK]

Common Mistakes:

MISTAKES

Thinking DP is needed due to 'maximize' keyword
Trying backtracking which is inefficient
Ignoring sorting to optimize assignment

Trap Explanation:

PITFALL

Many candidates confuse 'maximize' with DP necessity, missing that greedy suffices here.

Interviewer Note:
