# [Number of Different Integers in a String](https://leetcode.com/problems/number-of-different-integers-in-a-string)

You are given a string `word` that consists of digits and lowercase English letters.

You will replace every non-digit character with a space. For example, `"a123bc34d8ef34"` will become `" 123  34 8  34"`. Notice that you are left with some integers that are separated by at least one space: `"123"`, `"34"`, `"8"`, and `"34"`.

Return *the number of **different** integers after performing the replacement operations on* `word`.

Two integers are considered different if their decimal representations **without any leading zeros** are different.

**Example 1:**
```
**Input:** word = "a123bc34d8ef34"
**Output:** 3
**Explanation:** The three different integers are "123", "34", and "8". Notice that "34" is only counted once.
```
**Example 2:**
```
**Input:** word = "leet1234code234"
**Output:** 2
```
**Example 3:**
```
**Input:** word = "a1b01c001"
**Output:** 1
**Explanation:** The three integers "1", "01", and "001" all represent the same integer because
the leading zeros are ignored when comparing their decimal values.
```
**Constraints:**

* `1 <= word.length <= 1000`
* `word` consists of digits and lowercase English letters.
