Exercise: best student

Write a function best_student(names, scores) that returns a tuple (name, score) for the student with the highest score. The score of student names[i] is stored in scores[i].

• best_student(["ann", "bob", "cid"], [90, 95, 80]) → ("bob", 95)
• best_student(["ann", "bob"], [88, 88]) → ("ann", 88)
• best_student(["eve"], [0]) → ("eve", 0)

Constraints: the lists have the same length, from 1 to 5 items; scores are integers from 0 to 100; if several students share the highest score, the function returns the one that comes first in the list.

Do not add extra imports unless the task says so explicitly.
