135 - Candy\. Hard There are `n` children standing in a line. Each child is assigned a rating value given in the integer array `ratings`. You are giving candies to these children subjected to the following requirements: * Each child must have at least one candy. * Children with a higher rating get more candies than their neighbors. Return _the minimum number of candies you need to have to distribute the candies to the children_. **Example 1:** **Input:** ratings = [1,0,2] **Output:** 5 **Explanation:** You can allocate to the first, second and third child with 2, 1, 2 candies respectively. **Example 2:** **Input:** ratings = [1,2,2] **Output:** 4 **Explanation:** You can allocate to the first, second and third child with 1, 2, 1 candies respectively. The third child gets 1 candy because it satisfies the above two conditions. **Constraints:** * `n == ratings.length` * 1 <= n <= 2 * 10⁴ * 0 <= ratings[i] <= 2 * 10⁴
