Please output the number obtained by adding a and b.
At the end of the line break, do not include extra characters, blank lines.
expmple1
1 1
result1
2
expmple2
0 99
result2
99
My code is:
input_lines = gets.chop
a = input_lines[0]
b = input_lines[1]
puts a + b
But it's not working, please help.
Add split to the chopped gets would work:
input_lines = gets.chop.split
a = input_lines[0].to_i
b = input_lines[1].to_i
puts a + b
Try it.
Check String doc.
More DRY way to do it:
input_lines = gets.chop.split.map(&:to_i)
a,b = input_lines
puts a + b
In this case the numbers inside input_lines already changed to Integers.

I want to make this simple program that returns the weight quantity by choosing the units. When I run the program it runs with no problems and asks the two questions in if but doesn't return the value
Here is my code:
puts "What is your starting weight and ratio unit?
1:kg.m/h
2:gm.m/s
3:mm.m/s"
inputing_unit = gets.chomp
puts "What is your ending weight and ratio unit?
1:kg.m/h
2:gm.m/s
3:mm.m/s"
ending_unit = gets.chomp
if inputing_unit == 1 and ending_unit == 1 then
puts "What is your weight?"
input_weight = gets.chomp.to_i
puts "What is your ratio?"
input_ratio = gets.chomp.to_i
puts "Your moving value is #{input weight * input_ratio}"
end
As I can see from that screenshot in the beginning of the description on pre-last line where is your puts statement there is a typo #{input weight * input_ratio}. You should change ...#{input weight... to ...#{input_weight... (with a dash).

Im aiming for a regex formula to return chunks of a string based on a character, if this string contains L1 then its going to be only one chunk, if L2 is found it would return 2 chunks, L3 = 3 chunks.
Example
Lets assume we have this string
"L2N1N1"
and we would like to get 2 string
"L2N1" and "L2N1N1"
Another example
"L3N1N1N2"
to return 3 strings
"L3N1" "L3N1N1" "L3N1N1N2"
Im using Ruby
"L3N1N1N2".sub(/L(\d)(?:N\d)+/) do |m|
$1.to_i.times.map { |i| m[0..3+2*i] }.join(' ')
end
#⇒ "L3N1 L3N1N1 L3N1N1N2"

I use the excellent faker gem to generate random words for my models. Eg. product.name = Faker::Lorem.word
Sometimes I need to generate a sentence, and I want the length of the sentence to
vary each time.
How to achieve this with ruby?
How about:
result = rand(max_size).times.map { produce_word }
Since you have not provided enough information, this is my approach, [*1..100].sample will return a random number between 1 and 100, so looping that times the string which is returned bya method named get_word will get stored in the array word_array
word_array = []
[*1..100].sample.times do
word_array << get_word
end

I need to sort the numeric data in a row/column while leaving space of missing values at scale of 1-5.
Like:
A B
13245 1_2_3_4_5
152.... 1_2_ _ _5
Try this UDF:
Function ModSort(Str As String) As String
Res = ""
For Iter = 1 To 5
If InStr(1, Str, CStr(Iter)) Then
Hold = CStr(Iter) & "_"
Else
Hold = " _"
End If
Res = Res & Hold
Next Iter
Res = Left(Res, 9)
ModSort = Res
End Function
Screenshot:
Let us know if this helps.
Not meant as a serious answer (UDF seems good enough) but appears possible with a formula:
=IF(LEN(SUBSTITUTE(A2,1,""))<LEN(A2),"1_"," _")
&IF(LEN(SUBSTITUTE(A2,2,""))<LEN(A2),"2_"," _")
&IF(LEN(SUBSTITUTE(A2,3,""))<LEN(A2),"3_"," _")
&IF(LEN(SUBSTITUTE(A2,4,""))<LEN(A2),"4_"," _")
&IF(LEN(SUBSTITUTE(A2,5,""))<LEN(A2),"5",)

I have this:
array = ["a","b","c"]
How do I get this:
"a","b","c"
I need to get the items out of the array, each double-quoted, separated by a comma.
array.collect { |a| "\"#{a}\"" }.join(",")
I'm just started to learn ruby, I guess:
return ["a","b","c"].map{|i| '"' + i + '"'}.join(",")
Might you want to get this:
irb(main):009:0> [1, 2, 3].map(&:to_s).join('","')
=> "1\",\"2\",\"3"
"a","b","c" this is not abject (these are 3 objects). But in ruby any code returns object value. So you should know what you want to get: 1 object (I returning string in this example) or various. If you want to get 3 objects you should extract array like this:
a, b, c = [1,2,3].map(&:to_s)
