algorithm - Time complexity pseudo code -
i want calculate time complexity of following code :
for(i=0;i<n;i++){ func(); . // other o(1) operations . } where func() has complexity of o(k).
the time complexity o(k*n) then.
ios - Assigning a value out of array of arrays, using section in Xcode -
this code: let servicebonnen = [[1,2,3],[4,5,6],[7,8,9]] //not real data func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell { let cell = tableview.dequeuereusablecellwithidentifier("namecell", forindexpath: indexpath) cell.textlabel!.text = servicebonnen[section][indexpath.row] return cell } but gives me error @ "section" point in line of code: cell.textlabel!.text = servicebonnen[section][indexpath.row] does know why won't compile, , proper solution? you need use section indexpath : indexpath.section your line should this: cell.textlabel!.text = servicebonnen[indexpath.section][indexpath.row]
