create linklist, with node having DATA which contain
information and NEXT which cointain address of next node.
The pointer START pointing to first node of linklist. PREV
pointer point to first node(where START point) and TEMP
pointer which point at last node(by traversing).

Swap data of TEMP and PREV. Now increment TEMP(TEMP=TEMP-
>NEXT) and decreament TEMP.
Repeat this untill TEMP=PREV

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 }
