Spell checkers, as a case study of search structures

I need help modifying the existing code I have to match the new requirements. I will send the codes and the full requirement upon request Here is some of what the code does: 1. Given a file containing a word set and another file containing input text, it can check spelling in the input text and report on misspellings, along with suggestions about potentially correct spellings. 2. Given a file containing a word set and another file containing input text, it can do the work of a spell checker without displaying a result, instead displaying the CPU time required to perform the task.
