c++ code :
class Solution {
public:
vector xorQueries(vector& arr, vector& queries) {
vector px;
vector res;
px.push_back(arr[0]);
for(int i=1;i

Can you please explain why my solution without prefix sum is getting accepted on leetcode and not giving TLE:
/**
* @param {number[]} arr
* @param {number[][]} queries
* @return {number[]}
*/
var xorQueries = function(arr, queries) {
const ans = []
for(let i=0;i

on leetcode even c++ brute force is getting accepted.
