# Number of Different Integers in a String

# 1805. 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 = “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. ```
