C :

#include <stdio.h>
int main(){
	int n,temp;
	int a[50];
	int i;
	scanf("%d",&n);
    for(i=0;i<n;i++)
		scanf("%d",&a[i]);
	for(i=0;i<n/2;i++){
		temp=a[i];
		a[i]=a[n-i-1];
		a[n-1-i]=temp;
	}
	for(i=0;i<n;i++)
		printf("%d ",a[i]);
	printf("\n");
	return 0;
}

C++ :

#include <stdio.h>
int main() {
	int dat[51];
	int n, i, temp;
	scanf("%d", &n);
	for (i = 0;i < n;i++)
		scanf("%d", &dat[i]);
	for (i = 0;i + i < n;i++) {
		temp = dat[i];
		dat[i] = dat[n - 1 - i];
		dat[n - 1 - i] = temp;
	}
	for (i = 0;i < n;i++)
		printf("%d ", dat[i]);
	puts("");
	return 0;
}

Pascal :

var
  n,i:longint;
  a:array[1..50] of longint;
begin
  readln(n);
  for i:=1 to n do read(a[i]);
  for i:=n downto 1 do write(a[i],' ');writeln;
end.

Java :

import java.util.Scanner;

public class Main {
	public static void main (String[] args) {
		Scanner in=new Scanner(System.in);
		int n=in.nextInt();
	    int []a=new int[n];
	    for(int i=0;i<n;i++)
	    	a[i]=in.nextInt();
	    for(int j=n-1;j>=0;j--)
	    	System.out.print (a[j]+" ");
	    System.out.println ();
	}
}

Python :

b = int(input())
a = raw_input().split(" ")[::-1]
for j in range(0, b):
    print a[j],
print ""
