def find_range
  min = 0
  default_max = 99
  max = default_max
  goal = 4494
  while min <= max
    current_sum = (1..100).to_a[min..max].reduce(:+)
    if current_sum == 4494
      #We found it!
      break
    elsif current_sum > goal
      #Reduce the max
      max -= 1
    else #current_sum < goal
      #Reset the max and increment the min.
      min += 1
      max = default_max
    end 
  end

  puts "FOUND it.  MIN: #{min} MAX: #{max}" if min <= max 
  puts "NO CLUE!!" if min >= max 
end

puts find_range

nice code.

I just worked through this same problem and used the following code to solve the problem:

def finder(target)
    arr = (1..100).to_a

    arr.each do |i|

        arr.each do |x|

            if arr[i..x].reduce(:+) == target
                return puts "Range is #{i}..#{x}"
            end

            x += 1

        end

        i += 1

    end

end

finder(4494)
