# 1933. Check if String Is Decomposable Into Value-Equal Substrings

<https://leetcode.com/problems/check-if-string-is-decomposable-into-value-equal-substrings>

## Description

A **value-equal** string is a string where **all** characters are the same.

* For example, `"1111"` and `"33"` are value-equal strings.
* In contrast, `"123"` is not a value-equal string.

Given a digit string `s`, decompose the string into some number of **consecutive value-equal** substrings where **exactly one** substring has a **length of** `2` and the remaining substrings have a **length of** `3`.

Return `true` *if you can decompose* `s` *according to the above rules. Otherwise, return* `false`.

A **substring** is a contiguous sequence of characters in a string.

**Example 1:**

```
**Input:** s = "000111000"
**Output:** false
**Explanation:** s cannot be decomposed according to the rules because ["000", "111", "000"] does not have a substring of length 2.
```

**Example 2:**

```
**Input:** s = "00011111222"
**Output:** true
**Explanation:** s can be decomposed into ["000", "111", "11", "222"].
```

**Example 3:**

```
**Input:** s = "011100022233"
**Output:** false
**Explanation:** s cannot be decomposed according to the rules because of the first '0'.
```

**Constraints:**

* `1 <= s.length <= 1000`
* `s` consists of only digits `'0'` through `'9'`.
