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
