Java:

//Write your code here public static List dynamicArray(int n, List> queries) { // Write your code here

    List<List<Integer>> temp = new ArrayList<>();
    List<Integer> sol = new ArrayList<Integer>();

    for(int i=0; i<n; i++){
        temp.add(new ArrayList<>());
    }

    int lastAnswer = 0;

    for(List<Integer> query: queries){

        int type = query.get(0);
        int x = query.get(1);
        int y = query.get(2);

        int idx = (x ^ lastAnswer) % n;

        if(type == 1){
            temp.get(idx).add(y);
        }
        else if(type == 2){
            lastAnswer = temp.get(idx).get( y % temp.get(idx).size() );

            sol.add(lastAnswer);
        }

    }

    return sol;

need sujestion about dynamic errors created

C#

Here you should do exactly what they have explained at the top with the variable decleration. You can get some idea if you refer the given example properly.

public static List<int> dynamicArray(int n, List<List<int>> queries)
{
	var len = queries.Count();
	var arr = new List<List<int>>();
	
	for (int i = 0; i < n; ++i)
		arr.Add(new List<int>());
		   
	var lastAnswer = 0;
	var answers = new List<int>();

	for (int i = 0; i < len; ++i)
	{
		var query = queries[i];
		var type = query[0];
		var x = query[1];
		var y = query[2];
		
		var idx = (x^lastAnswer)%n;
		
		if (type == 1)
			arr[idx].Add(y);
		else
		{
			lastAnswer = arr[idx][y % arr[idx].Count()];
			answers.Add(lastAnswer);
		}          
	}
	
	return answers;
}

Great stuff, Could you please have a look on my site and let me know what is the big problem you are facing in it.

Hi, Do anyone know why my output is working properly on vs code and other editor but here output in stdout is empty.`vector dynamicArray(int n, vector> queries) { vector> arr(n,vector()); int lastAnswer = 0; int q_no = queries.at(0).at(1); vector res;

for(int i=1; i<=q_no; i++){
    int query_typ = queries.at(i).at(0);

    int x = queries[i][1];
    int y = queries[i][2];
    int idx = (x^lastAnswer)%2;

    if(query_typ==1){
        arr[idx].push_back(y);
    } 
    else if(query_typ==2)
    {
        lastAnswer = arr[idx][y];
        res.push_back(lastAnswer);
    }

}
return res;

}`
