This code is working on sample input and i checked it it works fine but it is not able to pass even a single test case can you please tell me where is my mistake

#1

#include
using namespace std;
int main() {
int row;
cin>>row;
int col;
cin>>col;

int n;
int rem;
int x=0;
int arr[100][100];
for(int i=0;i<row;i++){
	for(int j=0;j<col;j++){
		cin>>arr[i][j];
	}
}
while( x<row){
	if((x+1)%2!=0){
		for(int j=0;j<col;j++){
			int a=arr[x][j];
			int reverse=0;
			while(a!=0)    
          {    
         rem=a%10;      
         reverse=reverse*10+rem;    
          a=a/10;    
          }
		  arr[x][j]=reverse; 
		  cout<<arr[x][j]<<","<<" ";   
		}

	}
	else{
		for(int j=col-1;j>=0;j--){
			int a=arr[x][j];
			int reverse=0;
			while(a!=0)    
      {    
         rem=a%10;      
         reverse=reverse*10+rem;    
          a=a/10;    
          }
		   arr[x][j]=reverse;
		   cout<<arr[x][j]<<","<<" ";   
		}

	}
	x++;
}
cout<<"END";

return 0;

}
