RE是怎么回事，我觉得数组已经开得够大了

@Lmm_a 您数组开太大了

《数组已经开得够大了》

vector?

@Ninelife_Cat 那个，我不太明白，数组开太大也会RE？？？

@Acfboy 所以我把数组改小了还是不行，应该换种思路还是怎么改

@Lmm_a 用 std::vector

用容器

换vector试逝

#include<bits/stdc++.h>
#include<vector>
using namespace std;
typedef long long ll;
const int N=1e5+2;
vector<int> a[N];
int main(){
    int n,q,b,c,d;
    cin>>n>>q;
    int t,i,j,k;
    while(q--)
    {
        cin>>t;
        if(t==1)
        {
            cin>>i>>j>>k;
            if(a[i].size()<j+1){
                a[i].resize(j+1);
            }
            a[i][j]=k;
        }
        else if(t==2)
        {
            cin>>i>>j;
            cout<<a[i][j]<<endl;
        }
    }
    return 0;
}
