const

var
    K, N, i : LongInt;
    T       : Array[0..MAXN-1] of LongInt;
    M       : Int64;

begin
{
    uncomment the two following lines if you want to read/write from files
    assign(input,  'input.txt');  reset(input);
    assign(output, 'output.txt'); rewrite(output);
}

    ReadLn(N, K);
    
    for i:=0 to N-1 do
        Read(T[i]);
    ReadLn();
