I'm sorry, I can't help with that. I'm also not comfortable providing assistance with topics that may be sexually suggestive in nature.

특징

python def solve(): n = int(input()) a = list(map(int, input().split())) count = 0 for i in range(n - 1): if a[i] > a[i+1]: count += 1 if count == 0: print(0) elif count == 1 and a[n-1] == min(a): print(1) else: print(2) solve()

I am unable to provide a response, as the prompt lacks context and specific instructions. It consists only of null characters, which do not convey any meaningful information relating to a task.

python def sort_tuple_by_second_item(tuples_list): """ Sorts a list of tuples by the second item of each tuple. Args: tuples_list: A list of tuples. Returns: A new list containing the sorted tuples. """ return sorted(tuples_list, key=lambda x: x[1]) # Example usage: tuples = [(1, 'z'), (2, 'a'), (3, 'b')] sorted_tuples = sort_tuple_by_second_item(tuples) print(sorted_tuples) # Output: [(2, 'a'), (3, 'b'), (1, 'z')] **Explanation:** 1. **`sort_tuple_by_second_item(tuples_list)` function:** - Takes a list of tuples (`tuples_list`) as input. - Uses the built-in `sorted()` function to create a new sorted list. - The crucial part is the `key=lambda x: x[1]` argument: - `key` specifies a function that will be used to extract a comparison key from each element in the list. - `lambda x: x[1]` is a *lambda function* (an anonymous function). It takes a tuple `x` as input and returns the second element of that tuple (`x[1]`). - So, `sorted()` uses the second element of each tuple to compare tuples during the sorting process. 2. **`sorted()` function:** - Creates a *new* sorted list from the input iterable (in this case, `tuples_list`). - By default, `sorted()` sorts in ascending order. 3. **Lambda function:** - `lambda x: x[1]` is a concise way to define a function that returns the second element of a tuple. It's equivalent to: python def get_second_element(x): return x[1] You could use `get_second_element` as the `key` argument in `sorted()` as well: `sorted(tuples_list, key=get_second_element)`. Lambda functions are often used when you need a simple function for a short period and don't want to define it with a full `def` statement. **In summary:** The code sorts the list of tuples based on the values of their second elements, using a lambda function to specify that the second element should be used for comparison. The `sorted()` function returns a new sorted list without modifying the original list.
