Question 1: Write a program that replace all the occurrences of a specified string from a text file. For example: Text file has the follow sentence: Original text: Changes after you run your program: John is a smart student. Jennifer is a smart student. FYI: I attach a .txt file that you should use for this exercise. Lab 6 is similar to this exercise - instead of removing the word John - you are replacing by a name that the user is inputting into the program.
