My code is passing sample cases but failing All Test Cases... Any Hint

#1

This is my Code
include iostream
include algorithm
using namespace std;

//find first increasing than decreasing subarray
int fitdsa(int* arr, int n){

bool started = false;
bool decreasing = false;
int current_counter=0;
int max_count = 0;

for(int i=0; i<n; i++){
    if(arr[i]==1){
        if(!started){
            started=true;
            if(max_count<current_counter){
                max_count=current_counter;
            }
            current_counter=0;
            current_counter++;
        }
        if(started&&decreasing){
            started=true;
            decreasing=false;
            if(max_count<current_counter){
                max_count=current_counter;
            }
            current_counter=0;
            current_counter++;
        }
        if(started&&!decreasing){
            current_counter++;
        }
    }
    if(arr[i]==-1){
        if(decreasing&&started){
            current_counter++;
        }
        if(!decreasing&&started){
            current_counter++;
            decreasing=true;
        }
    }
    if(arr[i]==0){
        if(max_count<current_counter){
            max_count=current_counter;
        }
    current_counter=0;
    }
}
if(max_count<current_counter){
    max_count=current_counter;
}
return max_count;

}

int main(){
int t;
cin >> t;
while(t–){
int n;
cin>>n;
int* arr = new int[n];
int* idarr = new int[n];
int* diarr = new int[n];

diarr[i]=0;
}

idarr[i]=1;
diarr[i]=-1;
}
else if(arr[i]<arr[i-1]){
idarr[i]=-1;
diarr[i]=1;
}
else{
idarr[i]=0;
diarr[i]=0;
}
}
}

    int idmaxe = fitdsa(idarr, n); //Increasing Decreasing Max Element
    int dimaxe = fitdsa(diarr, n);
    int maxe = max(dimaxe, idmaxe);
    cout << maxe << endl;

    delete []diarr;
    delete []idarr;
    delete []arr;
}

return 0;

Please give me a minutes to look at your code

Hey @ajargrey You can solve the problem with much less lines of code and variables ,thus making it simpler to read and less prone to errors. Take a look at this c++ implementation https://ide.codingblocks.com/s/184439
