A seasonal artisan market cooperative asks every stall to self-report its net profit margin at the end of each year. Some stalls skip a year's report entirely, in which case that year is marked unreported rather than assumed to be zero. Before opening priority registration for next season's premium floor space, the market association wants the ids of every stall that was strictly profitable — reported a margin greater than zero — in one specific target year.

Input format

• Line 1 contains two integers n y: the number of ledger entries, and the target year to check.
• Each of the next n lines contains three space-separated tokens id year margin, where margin is either an integer or the literal token NA meaning that year was not reported for that stall.
• No stall has more than one entry for the same year.

Output format

Print, one per line and in strictly ascending order, every distinct stall id that has an entry for year y with a reported margin strictly greater than 0. Ignore entries for any other year and ignore NA entries entirely. If no stall qualifies, print nothing.

Constraints

• 1 <= n <= 10^5
• 1 <= id <= 10^9
• 1 <= y <= 10000, and every entry's own year also satisfies 1 <= year <= 10000
• when reported, -10^6 <= margin <= 10^6
