Create an object that will check the contents of a string for the most common character. It must return the character and the number of that character.

Most Common

def common(str)
  most = nil
  mcount = nil
	
  idx1 = 0
  while idx1 < str.length
    char = str[idx1]
    count = 0

    idx2 = 0
    while idx2 < str.length
      if str[idx2] == char
        count += 1 
      end
    
      idx2 += 1
    end

p "There are #{count} of #{str[idx1]}."

    if (mcount == nil) || (count > most)
      most = char
      mcount = count
    end

  idx1 += 1
  end

end

p common("electrical")
