returnN:{[orderColumn;order;N;tab]
// Determine the keywords associated with the ordering required
ascendingOrder: “asc”$order=“top”;
// Order the table by the column provided in ascending or descending order
ordered: tab order by orderColumn xasc ascendingOrder;
// Subset the first/last N records from the newly ordered table
result: ordered[N sublist orderColumn] if order=“top”
ordered[N # orderColumn] if order=“bottom”;
// Output table ordering should be in ascending order
result order by orderColumn xasc orderColumn;
}
if someone helped with the solution it will be helpful for me
