LeetCode 557. Reverse Words in a String III (easy)

Introduction: Unraveling the Mystery of LeetCode 557

Welcome, fellow coding enthusiasts! Today, we're diving headfirst into the fascinating world of LeetCode, specifically exploring the problem known as "LeetCode 557: Reverse Words in a String III (easy)." We'll break down this challenge, explore how to solve it, and provide you with a clear and practical example to help you master it.

Understanding the Challenge

Before we embark on our coding adventure, let's make sure we understand the challenge. In "LeetCode 557: Reverse Words in a String III," you're given a string containing words separated by spaces. Your task is to reverse the order of the characters in each word while still preserving the original order of the words themselves.

To put it simply, if we have a string like "Let's code on LeetCode," the expected output should be "s'teL edoc no teedoC."

A Step-by-Step Guide

Now, let's break down the solution into a series of steps that will make it easier to tackle.

Step 1: Split the String
Our first step is to split the input string into individual words. We can do this by using a built-in string split method. For example, in Python, you can use the split() function to achieve this.

python
# Split the string into words
words = input_string.split()

Step 2: Reverse Each Word
Once we have our words, it's time to reverse the characters in each word. We can use a simple loop to accomplish this.

python

# Reverse each word
reversed_words = [word[::-1] for word in words]

Step 3: Join the Reversed Words
Now that we have our reversed words, we need to join them back together into a single string. Again, Python's built-in functions come to the rescue.

python

# Join the reversed words
output_string = ' '.join(reversed_words)

Step 4: Return the Result
We're almost there! The last step is to return the final reversed string, and we're done.

python

``` Return the reversed string
return output_string

Putting It All Together: An Example
Let's bring it all together with an example. Suppose we have the input string "LeetCode is awesome."

We split it into words: ["LeetCode", "is", "awesome."]
We reverse each word: ["eteoCLe", "si", ".emosewa"]
We join the reversed words: "eteoCLe si .emosewa"
And there you have it! We've successfully reversed the words while preserving their order.

#Conclusion: You're a LeetCode Pro!
Congratulations! You've just conquered the LeetCode 557 challenge and learned how to reverse words in a string while keeping the word order intact. We've taken a seemingly complex problem and broken it down into simple, manageable steps.

Coding, like any other skill, becomes easier with practice. So keep on coding, and soon you'll be tackling even more challenging problems with confidence. Happy coding, and may your LeetCode journey be filled with success and learning!
