Accumulate Adding and Counting

The variable list is an array, it holds several integers. For example it might be the list {1,2,3,4}.

You can iterate over a list, every time you visit an element of the list you do something to the accumulator acc

In this example, for every member i of the list you add that member to the accumulator using the code

acc = acc + i;

Use the accumulator to count the number of items in the list:

Use the accumulator to find the product of items in the list:

Use the accumulator to find the largest item in the list:

acc = Math.max(acc,i);
