Inserting String At Position X Of Another String

When working with strings in programming, one common task is inserting a string at a specific position in another string. In this article, we will explore how to achieve this in various programming languages like Python, JavaScript, and Java.

Let's start with Python. In Python, strings are immutable, meaning you cannot change them in-place. To insert a string at a specific position in another string, you can create a new string by concatenating the substrings before and after the desired position with the string to be inserted. Here's an example:

def insert_string_at_position(original_str, position, string_to_insert):
    return original_str[:position] + string_to_insert + original_str[position:]

result = insert_string_at_position("Hello World", 6, "there ")
print(result)  # Output: Hello there World

Next, let's look at how you can achieve this in JavaScript. JavaScript, unlike Python, allows you to manipulate strings directly. You can use the `substring()` method to insert a string at a specific position in another string. Here's how you can do it:

function insertStringAtPosition(originalStr, position, stringToInsert) {
    return originalStr.slice(0, position) + stringToInsert + originalStr.slice(position);
}

let result = insertStringAtPosition("Hello World", 6, "there ");
console.log(result);  // Output: Hello there World

Lastly, let's cover how you can insert a string at a specific position in Java. In Java, strings are immutable, similar to Python. You can use the `substring()` method to achieve this. Here's an example:

public class Main {
    public static String insertStringAtPosition(String originalStr, int position, String stringToInsert) {
        return originalStr.substring(0, position) + stringToInsert + originalStr.substring(position);
    }

    public static void main(String[] args) {
        String result = insertStringAtPosition("Hello World", 6, "there ");
        System.out.println(result);  // Output: Hello there World
    }
}

In conclusion, inserting a string at a specific position within another string can be accomplished by manipulating substrings based on the programming language you are using. Whether you are coding in Python, JavaScript, or Java, the concept remains similar, and with the right approach, you can seamlessly insert strings at the desired position. Experiment with these examples and adapt them to suit your specific requirements in your coding projects.
