我已经编写了代码，但它显示第四大元素的输出不正确。让我知道我该怎么办？

test=[4, 6, 9, 4, 3, 88, 3, 2]
test.sort()
print("Original list: ",test)
res=[]
for i in test:
    if i not in res:
             res.append(i)
print("Removing duplicates: ",res)
print("4th largest element: ",test[-4])

回答

test = [4, 6, 9, 4, 3, 88, 3, 2]
fourth = sorted(test)[-4]
print(fourth)

test = [4, 6, 9, 4, 3, 88, 3, 2]
fourth = sorted(set(test))[-4]
print(fourth)
