I'm trying to add 3 integer values together through an array list to average them. What I have so far is down below, but need
help figuring out the blanks.

ArrayList<BigInteger> bigInts = new ArrayList<BigInteger>();
bigInts.add(new BigInteger("2333455236787456"));
bigInts.add(new BigInteger("234565764"));
bigInts.add(new BigInteger("979878678675"));

BigInteger average = new BigInteger("____");
for(int i = _____; i < bigInts.___(); i++){
average = average.____(bigInts._____(i));
}
BigInteger count = new BigInteger(""_____ bigInts._____());
average = average._____(count);
System.out.println(average);

We generally don't just hand out a homework answer, and that is clearly what this is. So why don't you try, and tell us what you got?


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
