	{
	
	int n = Integer.parseInt(br.readLine());
	for(int i=0;i<n;i++)
	{
	for(int j=0;j<=i;j++)
	arr[i][j]= Integer.parseInt(br.readLine());

Take this as a hint…
The problem you are getting is while taking input!!While running on ideone,it gives number format exception!!
Here is a link link text
Number format exception occurs when u try to convert a string into Number and when string is not appropriate.
The string should not contain any blank spaces…Hope this helps…
Try some other method as an input!!

I think @shivam217 is trying to solve SUMTRIAN.

@shivam217 It’s giving NZEC error because of this line: arr[i][j]= Integer.parseInt(br.readLine());
In the input you’ll have to read multiple numbers in a single line. That code only works when the line you’re currently reading only has one number and nothing else.
