Yeah it can't solve novel questions. The AI couldn't do much to solve this one for example:

ChatGPT is just a very good copy/paste, not a logical problem solver(yet).

I used 'z' instead of 'a' to avoid any possible issues with the article 'a'. I think I messed up the assignment of z[l] at z[r] being after its updated, not sure.
But it created the input format, described it and the program ran the first time once i fixed the indents (code formatting is broken for some reason). If I run against the input at the contest page I get NO NO NO NO YES.
> It just says to use the value from the first element, but it’s unclear if it’s before or after that first element is replaced by the first operation.
Is the following python code unclear to you?
a = 0 b = 1 a, b = b, a
or alternatively:
a = [1,2,3,4,5] a[0:3] = a[1:3] + [a[0]]
There's nothing in the statement that indicates the assignments should be done one element at a time (if so, the order of the assignments would need to be specified). It's an atomic operation that circularly shifts the values in the array in the range l...r
