WebThe first line of each test case contains the integers n and k ( 1 ≤ n ≤ 2 ⋅ 10 5, 1 ≤ k ≤ n) — the length of the array a and the minimum amount of times each number in the range [ l, r] should appear respectively. Then a single line follows, containing n integers describing the array a ( 1 ≤ a i ≤ 10 9 ). It is guaranteed that ...
