HELP RAHUL TO SEARCH

#1

I am pasting code here, I am unable to understand for which scenario is it failing, Please help me resolve it:

import java.util.*;
public class Main {
public static void main(String args[]) {
// Your Code Here
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int[] arr = new int[n];

	for(int i=0;i<n;i++){
		arr[i] = sc.nextInt();
	}

	int m = sc.nextInt();

	int ans = binarySearch(0,arr.length-1,m,arr);
	
	System.out.print(ans);
}

public static int binarySearch(int lo,int hi,int m,int[] arr){

	int mid = 0;

	while(lo<=hi){
		mid = (lo+hi)/2;
		if(arr[mid] == m){
			return mid;
		}else if(arr[lo]<=arr[mid]){
			if(m>=arr[lo] && m<=arr[hi])
			hi= mid-1;
			else{
				lo = mid+1;
			}
		}else{
			if(m>=arr[mid] && m<=arr[hi])
			lo = mid+1;
			else{
				hi=mid-1;
			}
		}
	}

	return -1;

}
