[algogeeks] Re: BST
You'd know how to do this if you had a sorted array A, right? Start a pointer at each end. Call the L and R. L = 0; R = length(A) - 1 while (L < R) { while (L < R && A[L] + A[R} > k) --R; if (A[L] + A[R} == k) return ; ++L; } return Since you have a BST, just replace L and R with iterators that scan from left to right and right to left through the tree. The ammortized cost of an iterator call is O(1), and there are clearly O(n) calls, where n = lengh(A). The iterators can each contain a O(log n) stack, but you seem willing to ignore log n stack space. You could get rid of the stacks by threading the tree.

[algogeeks] Re: Bitwise Ternary operator
This is impossible in C. The ternary operator as you've given it evaluates either y or z depending on the value of x. A C function call always evaluates all of its arguments. For example. int w, x = 1, y = 1, z = 1; w = x ? ++y : ++z; printf ("%d %d %d\n", y, z); will print 1 2 1. If you subsitute, w = cond(x, ++y, ++z); for the ternary operator, you'll get 1 2 2. This may sound like a small thing, but conditional/lazy evaluation is what leads to the power of Turing completeness in a language.

[algogeeks] Re: memory allocation
Create your own malloc() & free() functions. when you allocate memory, allocate a little bit extra memory to add a token of your choosing. When free'ing the memory, check that the token is still there. You are going to want to add the token to the beginning of the memory, and not at the end for 2 reasons: 1. When free'ing, you don't know how much memory was allocated, so it would be difficult to find the end of the memory. 2. If there was a buffer overflow error in the application, it would likely overwrite your token if it were at the end. The other thing to consider is that depending on your compiler flags, memory allocations typically occur at word boundaries to help improve speed. Therefore, it would be helpful for the token added to be a boundary supported by your compiler. It is still possible that if there is a buffer overflow error in your application, the token can still be wiped out. Below are some sample functions that could implement this algorithm. I used the address of the memory allocated as my token. I take the MAX between sizeof(void*) and sizeof(long long) to ensure that the token size will be compatible with the alignment of most architectures. However, you might want to tune this to work better (or to work at all) for your architecture. #define MAX(a,b) (a > b ? a : b) #define TOKEN_LEN MAX(sizeof(void*), sizeof(long long)) void *my_malloc(size_t size) { void *p = malloc(size + TOKEN_LEN); if(p != NULL) { ((void*)*p) = p; p += TOKEN_LEN; } return p; } void *my_free(void *p) { if(p!=NULL) { p -= TOKEN_LEN; if( ((void*)*p) != p ) // ERROR: Trying to free memory not allocated by my_malloc() -OR- there was a buffer overflow error else free(p); } else { // ERROR: Trying to free NULL } } On Jul 24, 2:08 pm, "dreamer " wrote: > Write a code that will check whether the memory allotted to the > program at the initial and the memory returned to the system is same > or not. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

[algogeeks] Re: BST
It is simple to convert BST to sorted doubly link list Just do inorder_traverse and add node into the linklist. It is like following. linklist_node *head=NULL; mod_in_order(tree_node *root){ tree_node *temp; temp=root; if (root is a leaf node) add_node_to_linklist(root); // instead of printing add node else { if(root->left) inorder(root->left); add_node_to_linklist(root); // instead of printing add node if(temp->right) inorder(root->right); } } On Jul 25, 2:27 pm, jalaj jaiswal wrote: > @ above have it > node * bsttolist(node *root){ > if(root==NULL) return NULL; > node *l=bsttolist(root->left); > node *r=bsttolist(root->right); > root->left=root; > root->right=root; > append(l,root); > append(l,r); > return l; > > } > > here append function merges two circular doubly linked lists , you can make > that on your own > > On Sun, Jul 25, 2010 at 1:35 PM, Debajyoti Sarma > wrote: > > > > > @rahul > > how to convert bst ot doubly linked list. > > I m understanding the logic but not able to code > > give a pseudo code to understand. > > > -- > > You received this message because you are subscribed to the Google Groups > > "Algorithm Geeks" group. > > To post to this group, send email to algoge...@googlegroups.com. > > To unsubscribe from this group, send email to > > algogeeks+unsubscr...@googlegroups.com > > . > > For more options, visit this group at > >http://groups.google.com/group/algogeeks?hl=en. > > -- > With Regards, > Jalaj Jaiswal > +919026283397 > B.TECH IT > IIIT ALLAHABAD -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

Re: [algogeeks] memory allocation
for this you shld make your own malloc function and while allocating memry count++ and while freeing count-- if count!=0 then there is memory leak .

Re: [algogeeks] Re: BST
@ above have it node * bsttolist(node *root){ if(root==NULL) return NULL; node *l=bsttolist(root->left); node *r=bsttolist(root->right); root->left=root; root->right=root; append(l,root); append(l,r); return l; } here append function merges two circular doubly linked lists , you can make that on your own On Sun, Jul 25, 2010 at 1:35 PM, Debajyoti Sarma wrote: > @rahul > how to convert bst ot doubly linked list. > I m understanding the logic but not able to code > give a pseudo code to understand. > > -- > You received this message because you are subscribed to the Google Groups > "Algorithm Geeks" group. > To post to this group, send email to algoge...@googlegroups.com. > To unsubscribe from this group, send email to > algogeeks+unsubscr...@googlegroups.com > . > For more options, visit this group at > http://groups.google.com/group/algogeeks?hl=en. > > -- With Regards, Jalaj Jaiswal +919026283397 B.TECH IT IIIT ALLAHABAD -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.

@rahul how to convert bst ot doubly linked list. I m understanding the logic but not able to code give a pseudo code to understand. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
