Hey @anitagupta1411

#include<iostream>
using namespace std;
void nextgreater(int* a,int n){
	for(int i=0;i<n;i++)
	{   
		int j=(i+1)%n; //updated
		while(j!=i)  //updated
		{
			if(a[j]>a[i]){
				cout<<a[j];
				if(i!=(n-1)){
					cout<<" ";
				}
				break;
			}
			j=(j+1)%n;
		}
		if(j==i){ //updated 
			cout<<"-1";
			if(i!=(n-1)){
					cout<<" ";
				}
		}
	}
}
int main() {
	int n;
	cin>>n;
	int a[n];
	for(int i=0;i<n;i++)
	{
		cin>>a[i];
	}
	 nextgreater(a,n);
	return 0;
