Rankings are determined by the number of problems solved, and ties are broken by the time at which the problems are solved (earlier is better).\n\nDISCLAIMER:\nTo claim your prize you need to present a random question you solved in person.\n\nTo get inputs/output, you need to use system method for example\n\n##############################################\n\nPython:\n#INPUT:\nx \u003d int(input())
