10.0% Acceptance

In this lab, you will be working with a permutation `perm` of `n + 1` integers of all the integers in the range `[0, n]` and a related string `s` of length `n`. The relationship between `perm` and `s` is as follows:

• `s[i] == 'I'` if `perm[i] < perm[i + 1]`, and
• `s[i] == 'D'` if `perm[i] > perm[i + 1]`.

Your task is to reconstruct the permutation `perm` from the given string `s` and return it. If there are multiple valid permutations `perm`, return any of them.

In this lab, you will be provided with a partially working code. You have to create challenges based on the given code and evaluation script. You will also need to ensure that the evaluation script is working correctly for the challenges you create.

Here is a detailed example to help you understand the problem:

Example 1:

Input: s = "IDID"
Output: [0,4,1,3,2]

Example 2:

Input: s = "III"
Output: [0,1,2,3]

Example 3:

Input: s = "DDI"
Output: [3,2,0,1]
