Homework Python
Hi, I have to write a function which takes list of numbers >=0 and gives me back the second max number in the list. I cannot sort, change the list or import methods. If the list contains <2 elements it should give me 0 I have to iterate every element only once. Example: secondmax([2, 5, 1, 6, 3]) -> 5 secondmax([2]) -> 0 secondmax([]) -> 0 My Attempt: I tried to do smth but it is not much, thanks Def secondmax(*args): If type(args) is list: For x in args:

I think you should try with finding the max() first. Then, find a min() and assign it to a variable. Then iterate through the list and keep re-assigning the value if it is greater than the last one, but still lower than the max.
After the iteration is done, you will get the second max :)

1. Find the max number of the list
2. Iterate through the list returning numbers smaller than the max number
3. Print the new max number

O(n) without any built-in features:

The function max iterates too.
Is it allowed to use it?

I think this is still a bit underspecified. What is the expected result when the list contains 2 or more elements that are all equal?

Mostapha Amenchar your code is good but does not seem to solve the above problem. Thanks.

Sorry, I forgot to tell that I should iterate through every element only once
