Python

Write a program enables a user to enter three lowercase words and then finds the word that would come first alphabetically. For example, if the user inputs the words "pear", "grape", "watermelon", the program should output that "grape" would come first alphabetically.

2. Attempt this same problem, but now structure the conditional statements as a decision tree (e.g., using nested conditional statements to reduce the number of conditions to check).

3. Again, attempt this same problem, but now structure the program to find the first word alphabetically using sequential processing (e.g., a loop that continually accepts input values while tracking what is the first word alphabetically that we have seen so far).
