/*
1. The range is now 0-4 including 0 and including 4.
2. The range when adding +3 infront of r.nextInt(5) makes the range 3 - 7 now, including 7.
3. When you change the random number seed, the numbers generated are no longer randomized. They are the same.
4. Changing the seed to 1 made all the random numbers alike. They all had a 1 in them.
