Explanation:

You can split a string at a specified point and then concatenate the segments with the new substring in between to add a substring at that location. The sequential reasoning to accomplish this is as follows:

Logic Explanation:

  1. Identify the Position:
    • Determine the index at which you want to insert the substring.
  2. Split the Original String:
    • Split the original string into two parts:
      • The part before the insertion position.
      • The part after the insertion position.
  3. Insert the Substring:
    • Concatenate the first part, the substring to insert, and the second part.
  4. Return the Modified String:
    • The resulting string will be the original string with the substring inserted at the specified location.
