the number of trailing zeros in a factorial of a given number - Ruby

Question

Having a little trouble trying calculate the number of trailing zeros in a factorial of a given number. This is one of the challenges from Codewars- can\'t get mine to pass.

Answer 1

Here's a solution that is easier to read:

def zeros(num)
  char_array = num.to_s.split('')
  count = 0

  while char_array.pop == "0"
    count += 1
  end

  count
end
