Stack is a data structure ,a last in, first out (LIFO)
abstract data type.
A stack can have any abstract data type as an element, but
is characterized by only two fundamental operations: push
and pop. The push operation adds to the top of the list,
hiding any items already on the stack, or initializing the
stack if it is empty. The pop operation removes an item from
the top of the list, and returns this value to the caller. A
pop either reveals previously concealed items, or results in
an empty list.

You have given 2 array. You need to find whether they will create the same BST or not. For example: Array1:10 5 20 15 30 Array2:10 20 15 30 5 Result: True Array1:10 5 20 15 30 Array2:10 15 20 30 5 Result: False One Approach is Pretty Clear by creating BST O(nlogn) then checking two tree for identical O(N) overall O(nlogn) ..we need there exist O(N) Time & O(1) Space also without extra space .Algorithm ?? DevoCoder guest Posted 3 months ago # #define true 1 #define false 0 int check(int a1[],int a2[],int n1,int n2) { int i; //n1 size of array a1[] and n2 size of a2[] if(n1!=n2) return false; //n1 and n2 must be same for(i=0;ia1[i+1]) && (a2[i]>a2[i+1]) ) ) return false; } return true;//assumed that each array doesn't contain duplicate elements in themshelves }
