return s[0]
else:
m = Max(s[1:])
if m > s[0]: #put index 0 here

`m` is a single number, therefore it cannot be compared with `s` which is a `list`. Thus ... | This variant will reduce the stack size by slicing the problem in half at each level of the recursion, and recursively solving for both halves. This allows you to evaluate lists with thousands of elements, where the approach of reducing the problem size by one would cause stack overflows.

] | Yes, it's called `flexible array member`. It's usually used with dynamically allocated objects. However, you cannot return `Minefield` by value. The compiler will copy only `sizeof(Minefield)` data what is the size of object if length of array `Minefield::field` was `0`.
You can do:
