def same_frequencies(s): 
    letters = [0] * 256 
    lenn = len(s)

    for i in range(lenn): 
        if (s[i].isalpha()):
          letters[ord(s[i]) - ord('a')] += 1

    frequencies = 0
    for i in range(256): 
        if (letters[i] != 0): 
            frequencies = letters[i]
            break

    for i in range(256): 
        if (letters[i] != 0 and (letters[i] != frequencies)):
            return False

    return True
    

s = "aaabbbcccwww"
           
if (same_frequencies(s)):
    print("yes")
else:
    print("no")
