Run Errror-- This is the code giving run error for test cases, Running with the sample test case gives correct output

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
int num=0,st[];
int n=sc.nextInt();

 for(int i=1;i<=n;i++){
	 num=sc.nextInt();
	 	 st=new int[num+1];
 System.out.println("#"+num+" : "+fibonacci(num,st));
 
 }


}

public static int fibonacci(int n,int st[]){
	if(n==0)
	return 0;
	if(n==1)
	return 2;
	if(n==2)
	return 3;
    if(st[n]!=0)
	return st[n];
	else{
	int res=fibonacci(n-1,st)+fibonacci(n-2,st);
	st[n]=res;
	return st[n];
	}
}

}

Firstly, the logic is not correct. You haven’t accounted for the fact the there SHOULDN’T be two consecutive b’s. You have just hardcoded all the cases for the sample test, so it passes the sample test case.
