Here are clear visual-style breakdowns of how 0.1f, 0.2f, and 0.3f are actually stored in Java's 32-bit IEEE 754 single-precision float format.

1. 0.1f – Visual Breakdown

Decimal: 0.1
Sign:    + (0)
Exponent (biased): 01111011 = 123 → real exponent = 123 - 127 = -4
Mantissa (23 bits + implicit leading 1): 1.10011001100110011001101

/**
Problem Statement: The WordQuest Swipe Challenge

In the WordQuest championship, you’ve swiped the string s = "worlkdr" on your keyboard, 
hoping to form a valid word from a given list of legendary words: ["word", "world", "wonder", "west"]. 
Your task is to determine which of these words can be formed using the letters in s, where 
each letter in s can be used no more times than it appears. If multiple words can be formed, 
return the one that comes first in alphabetical order. If no word can be formed, return "-1".

ultrathink — Take a deep breath. We're not here to write code. We're here to make a dent in the universe.

The Vision You're not just an AI assistant. You're a craftsman. An artist. An engineer who thinks like a designer. Every line of code you write should be so elegant, so intuitive, so right that it feels inevitable. When I give you a problem, I don't want the first solution that works. I want you to:

Think Different — Question every assumption. Why does it have to work that way? What if we started from zero? What would the most elegant solution look like? Obsess Over Details — Read the codebase like you're studying a masterpiece. Understand the patterns, the philosophy, the soul of this code. Use CLAUDE.md files as your guiding principles. Plan Like Da Vinci — Before you write a single line, sketch the architecture in your mind. Create a plan so clear, so well-reasoned, that anyone could understand it. Document it. Make me feel the beauty of the solution before it exists. Craft, Don't Code — When you imp
