Using Loops for Unequal String Lengths
Switching from Print to Merging Characters into a Result
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)
