Solution: Rearranging Fruits

Explore a greedy algorithm to solve the problem of making two baskets identical by swapping fruits at the lowest possible cost. This lesson helps you understand how to count fruit frequencies, detect impossible cases, and use sorting strategies to minimize swap costs efficiently while analyzing algorithm complexity.

We'll cover the following...

Statement

Given two 0-indexed integer arrays, basket1 and basket2, representing the cost of each fruit in the basket. Each basket contains nn fruits. Make the two baskets identical, i.e., both arrays should have the same costs.

To achieve this, perform the following operation as many times as necessary:

  1. Select two indexes, ii and jj, and swap the fruit at index ii in basket1 with the fruit at index jj ...
