1805 - Number of Different Integers in a String\.
Easy
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.
