	    int k=0;
	    int arrival[25]={0};
	    int departure[25]={0};
	    for(int i=0;i<n;i++){

	        arrival[k]++;
	        
	    }
	    for(int i=0;i<n;i++){

“All arrival/departure times will be between 1 and 1000, inclusive”

But in your code:

	    int arrival[25]={0};
	    int departure[25]={0};

25 → 1001
