#find the second hight score number #print it out

#First do list of all of elements
arr = list(arr)
arr.sort()
#print(arr)

#remove duplicates
uniuque_elements = set(arr)
#print(uniuque_elements)

#find the second hight score number
max_value = max(uniuque_elements)

uniuque_elements.remove(max_value)
#print(uniuque_elements)

Something I got confused about while working on this problem was actually understanding what the term "runner-up score" means. This was a bit confusing for me. The second thing I wasn't sure about was how to create a list for the "arr." However, in the end, I understood that we do need to have a list. But did we convert the "arr" to a list?

print(max(uniuque_elements))
