Problem: Candy

Hard
40 min
Explore the candy distribution problem using greedy algorithms to allocate candies to children based on their ratings. Understand the rules and constraints, and learn to determine the minimum total candies required to meet the problem's conditions with an efficient approach.

Statement

You are given an array, ratings, where ratings[i] represents the rating of the i-th child standing in a line. Your task is to distribute candies to each child based on the following rules:

  1. Every child must receive at least one candy.

  2. Children with a higher rating get more candies than their neighbors.

Determine the minimum total number of candies you must distribute to satisfy the above conditions.

Constraints:

  • 11 \leq ratings.length 1000\leq 1000

  • 00 \leq ratings[i] 1000\leq 1000
