Anyone can help here ?
All given test cases as well as some possible test cases self made, are getting passed.
Still on submitting some boundary cases gets failed i think…

#include <bits/stdc++.h>
using namespace std;

int main() {
	int t;
	cin>>t;
	while(t--){
	    long n;
	    cin>>n;
	    long arr[n];
	    
	    for(long i=0;i<n;i++)
	    cin>>arr[i];
	    
	    long maxi=INT_MIN,mini=INT_MAX,fposn=-1,lposn=-1;
	    
	    for(long i=n-1;i>=0;i--){
	        if(arr[i]>maxi){
	            maxi=arr[i];
	            lposn=i+1;
	        }
	         mini=min(mini,arr[i]);   
	    }
	    maxi=INT_MIN;
	    for(long i=0;i<n;i++){
	        if(arr[i]>maxi){
	            maxi=arr[i];
	            fposn=i+1;
	        }
	            
	    }
	    
	   if(mini==maxi)
	    cout<<0<<endl;
	   else
	    cout<<abs((n/2) -abs(lposn-fposn))<<endl;
	}
	return 0;
}
