What format do they provide tasks for execution in?

The format of tasks for execution can vary greatly depending on the context, but they are usually provided in the form of:

• A textual description with clear requirements and conditions.
• A set of input data and expected output data for solution verification.
• Sometimes with a code template or function that needs to be implemented.

For example, in Python, a task can be formulated as:

# Implement a function that takes a list of numbers and returns their sum.

def sum_numbers(numbers):
    pass

Test cases for such a task might include input data like:

print(sum_numbers([1, 2, 3]))  # Expected result: 6

Thus, the format usually includes a task description, implementation requirements, and usage examples or tests.
