Answer 1

If you are doing it on web then you can push values in an array and then print the stored values in reverse order.

var a=[]; //declaring an array a.
var num=snapshot.numChildren(); //storing number of children in var num.
a.push(snapshot.val()); // pushing data in the array.
if (a.length==num){ //checking if length of array is same as number of children.
a.reverse(); //reversing the array elements.
for(i=0; i
