    answer:
    if(ansI == 1e9){
        puts("-1");
        return 0;
    }

    vector<int> cnt;
    int i = ansI, j = ansJ, m = ansM;
    while(i){
        if(DP[i][j][m-1]) m--;
        else{
            cnt.push_back(b[m]);
            j -= b[m], i--;
        }
    }

    vector<vector<int> > ans;
    for(int p: cnt){
        vector<pair<int, int> > vec;
        for(int i=1; i<=n; i++) vec.push_back(make_pair(a[i], i));
        sort(vec.rbegin(), vec.rend());
        ans.push_back(vector<int>());
        for(int i=0; i<p; i++) ans.back().push_back(vec[i].second), a[vec[i].second]--;
    }

    printf("%d\n", (int)ans.size());
    for(auto p: ans){
        printf("%d ", (int)p.size());
        for(auto x: p) printf("%d ", x);
        puts("");
    }
