@[zrz_orz](/space/show?uid=52295) 不行呀，用洛谷IDE光显示运行时错误，没用显示具体原因呀

```python
num_dict = {'1': 2, '2': 5, '3': 5, '4': 4, '5': 5, '6': 6, '7': 3, '8': 7, '9': 6, '0': 6}
def num_count(x):
a_list = list(str(x))
num_con = 0
for k in a_list:
num_con += num_dict[k]
return num_con
num = int(input())
result = 0
for i in range(750):
a = num_count(i)
for j in range(750):
b = num_count(j)
c = num_count(i+j)
if a + b + c == num-4:
result += 1
print(result)
```

@[lj24405](/user/251654) 你的num的key和list的下标是一样的，~~list他不香吗？~~
