C :

#include<stdio.h>
int main()
{
    int n;
	scanf("%d",&n);
	int a[n],i;
	for(i=0;i<n;i++){
		scanf("%d",&a[i]);
	}
	int max=a[0],x=0;
	int min=a[0],y=0;
	for(i=0;i<n;i++){
		if(a[i]>max){
				max=a[i];
				x=i;
			}else if(a[i]<min){
				min=a[i];
				y=i;
			}
    }
       printf("%d %d",x+1,y+1);
return 0;
}

C++ :

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

int main(){
	int a[1000],n,i,max = 0,min = 0;
	cin>>n;
	for(i = 0;i < n;i++){
		cin>>a[i];
		if(a[i] > a[max]){
			max = i;
		}
		
		if(a[i] < a[min]){
			min = i;
		}
	}
	
	cout<<max + 1<<" "<<min + 1<<endl;
}

Python :

n=int(input())
a=input().split()
a=list(map(int,a))
da=max(a)
dai=a.index(da)+1
xiao=min(a)
xiaoi=a.index(xiao)+1
print(dai,xiaoi)
