{ "task_id": "b73ca7334d4d77424a889a83b6b62aad9fae71ba", "task_index": 1, "instruction": "Solve the problem below by writing a Python program to `solution.py` in the current working directory (it does not exist yet, so create it with the `write` tool). The program must read its input from standard input (stdin) and write ONLY the required answer to standard output (stdout).\nThen TEST it against the example cases shown in the problem: run your program on each example input with bash, e.g. `printf '' | python3 solution.py`, and compare its output to the expected output. If an example fails or the program errors, use the `edit` tool to fix `solution.py`, then run it again. Keep going until your program passes all the provided examples, then stop.\n\nPROBLEM:\nA sequence $(b_1, b_2, \\ldots, b_k)$ is called strange, if the absolute difference between any pair of its elements is greater than or equal to the maximum element in the sequence. Formally speaking, it's strange if for every pair $(i, j)$ with $1 \\le i
