Step-by-step explanation:
In the short story "A&P" by John Updike, Sammy is a round (dynamic) character, while Lengel is a flat (static) character.
Sammy undergoes a significant change in the story. He starts off as a typical teenage boy working at the A&P grocery store, but when he observes the unfair treatment of the girls by his manager, Lengel, he decides to quit in protest. This decision demonstrates his growth and development throughout the story.
In contrast, Lengel remains the same throughout the story, maintaining his strict and authoritative demeanor as a store manager. He does not exhibit any significant change or development.
