+ * 3.25

+ * Just a note to myself, i first finished this
+ * exercise by making a begin variable and also a temporary
+ * variable and incrementing on the temporary one, but
+ * of course you can just do everything directly which
+ * created this ugly thing ++*(scores.begin() + grade / 10);
+ * A bit difficult to read, and i do wonder if its faster
