let denote median sequence s odd length value middle s sort s nondecrease order for example let s 1 2 5 7 2 3 12 after sort sequence 1 2 2 underline3 5 7 12 median equal 3you sequence n integer 1 2 dot n odd integer kIn step choose k element sequence erase choose element median these element continuously gap allow themfor example sequence 1 2 3 4 5 6 7 ie n7 k 3 follow option step possible choose 1 underline2 3 2 median erase result sequence 2 4 5 6 7 choose 2 underline4 6 4 median erase result sequence 1 3 4 5 7 choose 1 underline6 7 6 median erase result sequence 2 3 4 5 6 you zero step can sequence b_1 b_2 b_m stepsyoull give t test case Solve test case independently
