LeetCode Solution: 8. String to Integer (atoi)

From Characters to Numbers: Cracking LeetCode's "String to Integer (atoi)" Welcome, future coding wizards! 👋 Today, we're diving into a classic LeetCode problem that might seem straightforward at first glance but hides a surprising number of tricky edge cases: Problem 8, "String to Integer (atoi)" . If you've ever used a parseInt() function in JavaScript, int() in Python, or stoi() in C++, you know the basic idea: convert a string of digits into a numerical integer. LeetCode's myAtoi asks us to implement this ourselves, but with a precise set of rules that mimic how these functions often work internally. Let's break it down! The Problem: More Than Just Converting Digits Imagine you're building a calculator app, and users might type in numbers like "42" , " -042" , or even "1337c0d3" . Your app needs to convert these strings into actual numbers, but also handle unexpected inputs gracefully. The myAtoi(string s) function needs to perform the conversion following these specific steps: Whi
