Avoid wikipedia, anyone can put answers down on there and make it seem correct but it is not. Do not trust any website research the websites or look at ratings if possible. Use the answers that google provides itself if possible. And research trusted websites.
If this helped please mark me as brainlest.

Answer:
it stores the largest value in list (the maximum) in foo
Explanation:
Initially foo is assigned as the first element of the list
Inside the loop, every element in the list will be compared with foo, starting from the second element. If an element is greater than foo, the new value of the foo will be that element. At the end of the loop, foo will be equal to the largest element in the list.
