Hey @chitranshanmol07
So we have 2 stcks say s2 is empty and s1 contains 1 2 3 4 5 6 7 here 7 is top side
Now acc to our loop we do this
Initially
s1-> 1 2 3 4 5 6 7
s2 ->

1st iteration
s1-> 1 2 3 4 5 6
s2-> 7

2nd iteration
s1-> 1 2 3 4 5
s2-> 7 6

3rd iteration
s1-> 1 2 3 4
s2-> 7 6 5
and so on

7th iteration
2nd iteration
s1->
s2-> 7 6 5 4 3 2 1
