here's my code so far. I've tried everything to get the last part to work out. Basically, I want my program to print only the numbers up to 3407 where the last digit is equal to the sum of the rest of the digits. so 3407 WOULD print, but not 3406...

CODE


100.upto(3407) do |i|
str=i.to_s
arr=str.split("")
print i
print "\t"
sum=0
sum= arr[arr.length-1]
print sum
print "\t"
sum2=0
sum3=0
sum2=arr.each{|element|
        sum3+=element.to_i
        }
print sum3
print"\t"
sum4=0
sum4=((sum3.to_i)-(arr[arr.length-1].to_i))
puts sum4
puts "\t"



I know that I need to use an if statement, and I've tried " if sum==sum4" but that wasn't working. any suggestions? thanks :D im a beginner so im still taking this all in

If your issue is that you are getting an exception that looks something like:
QUOTE
projectname.rb:20: syntax error, unexpected $end, expecting kEND

Then it may have something to do with the following line of code.
ruby
arr=str.split("")

I do not think you can split a string without telling it where it needs to be split in any language. Try fixing that, it might just be the reason your code isn't working.
