# 0 ms C++ solution time limit exceeded

• I ran into a TLE, and when I copied the test case and pasted it into the custom test-case, it runs fine and states it has a run time of 0 ms. Don't know why I'm getting a TLE...

``````class Solution {
public:
vector<vector<int>> threeSum(vector<int>& nums) {
int length = nums.size();
vector<int>process;
unordered_map<int,int>check;
for(int i =0;i < length; i++){
if(check[nums[i]]<3){
process.push_back(nums[i]);
check[nums[i]]++;
}
}
nums = process;
length = nums.size();
sort(nums.begin(),nums.end());

set<vector<int>>nodups;
for(int i = 0; i<length-2; i++){
if(nums[i]>0)
break;
int start = i+1;
int end = length -1;
//cout<<nodups.size()<<endl;
while(start < end){
int sum = nums[i] +nums[start]+nums[end];
if(sum ==0)
{
nodups.insert({nums[i],nums[start],nums[end]});
start++;
end--;
//break;
}
else if(sum < 0)
start++;
else
end--;

}

}
int size = nodups.size();
vector<vector<int>>sol(size,vector<int>(3));
set<vector<int>>::iterator it;
int i =0;
for(it = nodups.begin();it != nodups.end(); it++){
sol[i] = (*it);
i++;
}
return sol;
}
};``````
