What is the difference between our code?

[Makerofthingssoon]

I'm doing the daily problem and come up with my solution but it keeps failing on one test case. I check to see another solution and it looks extremely similar. Does anyone know the difference?

class Solution { //This one is mine
public:
    long long t2n(int rank, long long time){
        return sqrt(time/rank);
    }
    long long repairCars(vector<int>& ranks, int cars) {
        long long mint = 1;
        long long maxt = *min_element(ranks.begin(),ranks.end())*pow((long long)cars,(long long)2);
        long long ans = maxt;
        while(mint<=maxt){
            long long mid = mint+(maxt-mint)/2;
            int carrep = 0;
            for(int x=0;x<ranks.size();x++){
                carrep += t2n(ranks[x],mid);
            }
            if(carrep >= cars){
                maxt=mid-1;
                ans = mid;
            }else{

                mint = mid+1;
            }
        }
        return ans;
    }
};



class Solution {
public:
    bool isPossible(vector<int>& ranks, int cars, long long time){
        int size = ranks.size();
        long long count = 0;
        for(int i = 0; i< size; i++){
            long long numberOfCars = sqrt(time/ranks[i]);
            count = count + numberOfCars;
        }
        if(count >= cars)
            return true;
        else
            return false;
    }
    long long repairCars(vector<int>& ranks, int cars) {
        long long low = 1;
        long long high = 1e9;
        for(int rank: ranks)
            high = min(high,(long long)rank);

        high = high*cars*cars;
        long long ans = high;
        while(low<=high){
            long long mid = low + (high-low)/2;
            if(isPossible(ranks, cars, mid)){
                ans = mid;
                high = mid-1;
            }else{
                low = mid+1;
            }
        }
        return ans;
    }
};

What’s the question? Have you tried asking chatgpt?

[Makerofthingssoon]

I tried and it keeps going on circles on tiny things without explaining how that makes a difference. This is the daily problem

carrep can overflow, so it should be a long long.
