# 1.打印出所有的1-1000中的 "水仙花数 "，所谓 "水仙花数 "是指一个三位数，
# 其各位数字立方和等于该数本身。例如153
# count=100
# while count<1000:
#     a = count // 100
#     b = count //10 % 10
#     c = count % 10
#     if count==a**3+b**3+c**3:
#         print(count)
#     count+=1

# count=100
# while count<1000:
#     a=count//100
#     b=count//10%10
#     c=count%10
#     if count==a**3+b**3+c**3:
#         print(count)
#     count+=1

# for i in range (100,1001):
#     s=str(i)
#     if int(s[0])**3+int(s[1])**3+int(s[2])**3==i:
#         print(i)
# for i in range(100,1001):
#     s=str(i)
#     if int(s[0])**3+int(s[1])**3+int(s[2])**3==i:
#         print(i)
#  for i in range(100,1001):
#      s=str(i)
#      if int(s[0])**3+int(s[1])**3+int(s[2])**3:
#          print(i)
