```
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellId = @"Cell";
    ContestQATableViewCell *cell =(ContestQATableViewCell *)[tableViewQA dequeueReusableCellWithIdentifier:cellId];
    if (cell==nil)
    {
        NSArray *myNib;
        myNib =[[NSBundle mainBundle]loadNibNamed:@"ContestQATableViewCell" owner:self options:nil];
        cell = (ContestQATableViewCell *)[myNib lastObject];
    }
    cell.question.text = [getContestQArray objectAtIndex:indexPath.row];
    NSString *str1 = [getAnswer1Array objectAtIndex:indexPath.row];
    NSString *str2 = [getAnswer2Array objectAtIndex:indexPath.row];
    NSString *str3 = [getAnswer3Array objectAtIndex:indexPath.row];
