Write a program that generates $30$ random numbers $($range $1-20$ inclusive$)$ and then writes the numbers to a file. Each number in the file should be separated by a $|$ symbol with five numbers per line. No line should begin or end with a $|$ symbol. The program should also write control totals on the last $2$ lines of the file, the second last line showing the average number generated, and the last line showing the number$($s$)$ that were generated the least amount of times.
