Что я уже пробовал:

Here is a huge code. You can copy and paste also but it is giving me segmentation error. How to avoide this? Because whenever I try to replace the text and update it in another file, it gives me segmentation error. As I am new here. So I am pretty confused how to solve this issue and replace the word properly.
