Predictable Randomness

Mission

Pseudo-random output with a fixed seed is reproducible and must not be used for cryptographic secrets. Flag generation code: import random random.seed(12345) flag_chars = [chr(random.randint(65, 90)) for i in range(10)] print("KINOCO{" + "".join(flag_chars) + "}") Run the same Python code and submit the flag it prints.
