How to remove empty element in an array

Hi all,

I have an array of [1,2,''] I want change it to [1,2]. I check the
document about Array but I cant't find a way to remove the empty
element. Any comments?

Thanks,

Li

You should really get hold of your copy of the Pickaxe.

It's "[1, 2, <empty-string>]"? If so, then it's not an empty element.
If you have [1, 2, nil] then you can just use Array#compact or
Array#compact!. Otherwise, look at #delete_if.

Hi,

Can you please help me on this issue, I have seen your mail id from ruby

I am using ruby program for summing up all the numbers from array.
Unfortunately it is returning two values instead of one value.??
Can you please help me on this....

I appreciate your help on this..:slight_smile:

Input to array:
9989
9991
19980 -> it summing above two numbers
9990
9989
19979 -> it is summing these two numbers

all 4 numbers shoud add and retunr one value but , my ruby program
returning two values saparately(19980 ,19979 )

sum.rb code

···

----
module Enumerable
# sum of an array of numbers
def sum
return self.inject(0){|acc,i|acc +i}
end
end # module Enumerable
numbers = []
print "\n"
ARGV.each { |num|
i = Float(num)
numbers << i
}
#n=numbers.sum.to_i
#print n.to_s.gsub(/(\d)(?=\d{3}+(?:\.|$))(\d{3}\..*)?/,'\1,\2')
print numbers.sum.to_i
#print "\n"

You should pastie your code somewhere.

Example:

http://pastie.org/

It's hard to help without seeing the code. Also you should start a new
thread, right now this thread is muddled with another thread ...

I put you code into a file called x and ran it

$ ruby x 9989 9991 9990 9989

39959[~]$

Seems to be working here, cant think why it shouldn't

What is "it"? Please do not hijack old threads.

Kind regards

robert
