For the contest - CodeWars 2.0 CWR22021 , in the question Chef and Rabbits, the code I have written passed all the test cases, but I am getting an NZEC error on submission. Here is the code.
Can someone please help me out…

int T = sc.nextInt();

	while(T-->0){
		int hops = 0;
		int N = sc.nextInt();			
		int arr[] = new int[N];
		
		for(int i=0;i<N;i++)
			arr[i] = sc.nextInt();
		
		int currPos = 0;
		int largePos = 0;
		int i=0;
		int flag=0;
		while(true && currPos <=N-1){	
			int p1=0,p2=0, j=0;
		 // currValue = arr[i];
		  
		  p1 = i+1;
		  p2 = i+arr[i];
		  
		  if(p2>=N-1){ // if I can reach the end of the array
			  hops++;
			  flag++;				  
			  break;
		  }

		  //finding the largest in the subarray -- beg
		    int large= -1;
		  for(j=p1;j<=p2;j++)
			  if(arr[j]>large){
			   large = arr[j];
			   largePos = j;
			  }
		//finding the largest in the subarray -- end
		  
		  if(large == 0)
			  break;
		  
		  hops++;
		  i=largePos;
		  currPos = largePos;
		}
		
		if(flag==1||currPos>=N)
			System.out.println(hops);
		else
			System.out.println(-1);
	}
