}

// With the "1 +" at the beginning of the line removed, the random number generator yields a range of 0-4, not 1-5.
// When the "1 +" is changed to "3 +", it generates numbers in a range of 3-7.
// When the random number seed was set to a specific value, the "random" numbers were the same each time.
