初めてのRuby 読書メモ

動く擬似コード

(2..100).each do |candidate| # 2から100までのそれぞれ(each)について、順に素数の候補(candidate)として扱う
sqrt = Math.sqrt(candidate) # 候補の平方根(square root)を取る
factor_found = (2..sqrt).any? {|i| candidate % i == 0} # foctor_found = 2から平方根までのいずれかのanyが、candidate % i == 0となる

if factor_found then
  print "#{candidate}は合成数\n"
else
  print "#{candidate}は素数\n"
