b = {a:100, c:300, b:200}
  
# declaring Hash value
c = {a:100}
  
  
# to_hash Value
puts "Hash a to_hash form : #{a.to_hash()}\n\n"
  
puts "Hash b to_hash form : #{b.to_hash()}\n\n"
  
puts "Hash c to_hash form : #{c.to_hash()}\n\n"

Hash a to_hash form : {:a=>100, :b=>200}

Hash b to_hash form : {:a=>100, :c=>300, :b=>200}

Hash c to_hash form : {:a=>100}
