How can we reverse a stack by using only push() and pop() operations without using any secondary DS?
I'm trying to figure out how to reverse a stack using only push() and pop() operations without using any secondary data structure. Do you have any ideas?
Yes, reversing a stack using only push() and pop() operations without using any secondary data structure is a bit tricky. One approach could be to use two additional stacks to reverse the elements of the original stack. Would you like me to explain this approach in more detail?
