二维数组C1中，下图算式的结果是（ ）

计算 (\sum_{i=1}^{10} C1[10][i])

#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
ll C1[35][35];

void init(){
    for(int i = 0; i <= 34; i++){
        C1[i][0] = 1;
        for (int j = 1; j <= i; j++){
            C1[i][j] = C1[i - 1][j] + C1[i - 1][j - 1];
        }
    }
}

ll CC(ll n, ll m){
    ll ans = 1;
    for (ll i = n; i > n - m; i--)ans = ans * i;
    for (ll i = m; i >= 1; i--)ans = ans / i;
    return ans;
}

int main(){
    init();
    ll n, m;scanf("%lld%lld", &n, &m);
    printf("%lld %lld", C1[n][m], CC(n, m));
    return 0;
