Inserting a string at a specific index is a common operation in programming. Different programming languages offer various methods to achieve this. Below, we will explore how to perform this task in Python, JavaScript, Java, and C.

Python

In Python, strings are immutable, which means they cannot be changed after they are created. To insert a string at a specific index, you need to create a new string that includes the desired insertion.
