hash表记录每个字母出现次数，加上贪心。
n = eval(input())
for i in range(n):
s = input()
num_dict = {}
for j in s:
if j in num_dict:
num_dict[j] += 1
else:
num_dict[j] = 1
# only using the number of the alphabet
res = 0
num_list = sorted(num_dict.values(),reverse = True)
for i in range(len(num_list)):
res+=(26-i)*num_list[i]
print(res)
