# 1.输入小写单词并转为列表
a=input()# 输单词：aASSDSSDFssscvbn
b=list(a.lower()) # 转为小写字母再变成列表赋值给b
# print(b)
# 2.统计字母出现的个数
counts={} # 定义空字典
for word in b:# 2行代码统计次数
counts[word] = counts.get(word,0) + 1
print(counts)
# 最大值减最小值 counts.values() 获取数值
distance = max(counts.values()) - min(counts.values())

#判断质数：大于1的数，除1与本身无法被整除
