Given elements of a stack, clone the stack without using extra space.


Example 1:

Input:
N = 10
st[] = {1, 1, 2, 2, 3, 4, 5, 5, 6, 7}
Output:


Your Task:  
You don't need to read input or print anything. Your task is to complete the function clonestack() which takes the input stack st[], an empty stack cloned[], you have to clone the stack st into stack cloned.
The driver code itself prints 1 in the output if the stack st is cloned properly and prints 0 otherwise.


Expected Time Complexity: O(N*N)
Expected Auxiliary Space: O(1)

 

Constraints:
1 <= N <= 1000

1<= st[i] <= 105
