LeetCode 1768: Merge Strings Alternately Explained | C++, Java, Python

Описание: 🔍 *Two Sum Problem Explained*
Welcome back, coders! 🚀 In this video, we dive into a simple yet insightful problem from LeetCode: Merge Strings Alternately. We build our approach step by step from a basic idea to a clean and efficient implementation.

Here's what I cover in the video:
1️⃣ *Printing One String Letter by Letter*
2️⃣ *Handling Two Strings with Alternating Print Statements*
3️⃣ *Using Loops for Unequal String Lengths*
4️⃣ *Switching from Print to Merging Characters into a Result*
5️⃣ *Final Code in C++, Java, and Python*

🧠 *Step-by-Step Intuition*

*Printing One String*
We start with the most basic form of iteration—printing one character at a time from a single string. This helps us understand the core structure.

*Two Strings - Alternating Characters*
What happens when you have two strings? Imagine alternating their characters using two print statements inside a loop: print(s1[i]), print(s2[i]).

*Handling Extra Characters*
When one string is longer than the other, we add extra loops to print the remaining characters.

*Merging Instead of Printing*
In the final solution, we replace print with merge logic—adding characters to a result string instead of printing them. This gives us the merged string as the final output.

🧪 Code Implementation

We write a simple loop to iterate over both strings up to the length of the shorter one, then add the remaining characters from the longer string. The result is a clean, readable, and efficient solution.

*Complexity*
Time Complexity: O(m + n)
Space Complexity: O(1)
