# Greetings SQL Guru!
#
# The task is to write code that mimics the computation of a few SQL queries.
# Don't worry, you don't have to write a parser! Just read in a comma delimited
# flat file 'input.txt' and output the results of the following queries:
#
#   select state,count(*) from table group by state order by count(*) desc
#   select round(avg(age),1) from table
#   select state,round(avg(age),0) from table group by state order by avg(age)
#   select state,round(avg(age),0) from table where age > 15 AND age < 55 group by state order by state

# Welcome to FizzBuzz!
#
# The task is to print out the numbers 1 through 100. The exception being the following:
#
# - If the number is divisible by 3, print Fizz
# - If the number is divisible by 5, print Buzz
# - If the number is divisible by 3 and 5, print FizzBuzz
#
# You can write the solution in any language provided that any compilation or setup is
# done in the 'build' script and the command to run the solution is named 'fizzbuzz'.
