最简单的方法,找到最大的数,然后循环生成数组即可
python
class Solution:
def printNumbers(self , n: int) -> List[int]:
max_num = int('9' * n) //直接拼出来,转int即可
return [i for i in range(1, max_num+1)]
c++
class Solution {
public:
vector<int> printNumbers(int n) {
float max_num = pow(10.0, (float)n); //10的n次方再减1就是n位数的最大数
vector<int> res;
for(int i=1; i<max_num; i++){ //循环放进容器即可
res.emplace_back(i);
}
return res;
}
};
