Understanding the Number of Different Integers in a String Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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.

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