Integer numWeights is read from input. Then, numWeights integers are read from input and inserted at the end of weightList. Assign sumOfWeights with the sum of all the elements in weightList.

Ex: If the input is:

$3$

$423129$

then the output is:

$102$

import java.util.Scanner;

import java.util.ArrayList;

public class WeightListSum $\{$

public static void main$($String$[]$ args$)\{$

for $($i $=0$; i $<$ numWeights; $++$i$)\{$

$\}$

$/*$ Your code goes here $*/$
