The last was 32 but then we changed the value of [2](which is the last one) to 20 and it was still 32. Any reason why?

csharp> lockCombination[2] = 20;
csharp> last
32
csharp> lockCombination
{ 10, 5, 20 }

So the first thing that can be tricky is, if you have [2] it is actually referring to the third item in the list. so for list [0, 5, 17], list[2] would be 17. But, unless I'm mistaken, the part that is giving you trouble is that you have two different variables here. One named last, with a value of 32, and one called lockCombination. When you wrote

csharp> lockCombination[2] = 20;

it did indeed change the value of lockCombination[2] to 20. You can see that by looking at the value of the third value of your output

csharp> lockCombination { 10, 5, 20 }

however, this did not change the value of last, so it is still 32. If you wanted to also change the value of last to 20, you would need to write something like last = 20;

Hope that helps.
