The three loop problem is quite simple, how to use two pointers to solve this problem ?

int threeSumSmaller(vector<int>& nums, int target) {

```
int n = nums.size();
sort(nums.begin(),nums.end());
int count = 0;
for(int i=0; i<n-2; i++){
for(int j = i+1; j<n-1; j++){
for(int p = j+1; p<n; p++){
int sum = nums[i] + nums[j] + nums[p];
if(sum < target){
count++;
}else{
break;
}
}
}
}
return count;
}
```
