he entry in the nth row and kth column of Pascal's triangle is `N choose k`

. As a reminder, n and k starts from `0`

.

I wrote a simple function for N choose K and as you can see the solution is pretty straightforward.

Please let me know if you have any questions.

```
class Solution {
private:
double n_choose_k(int n, int k){
double result = 1;
for (int i = 1; i <= k; i++)
{
result *= n-i+1;
result /= i;
}
return result;
}
public:
vector<int> getRow(int rowIndex) {
vector<int> res;
for (int i = 0; i< rowIndex+1; i++) res.push_back(n_choose_k(rowIndex,i));
return res;
}
};
```
