[algogeeks] Find the path in two nodes of a binary search tree
Suppose you have a tree. A binary tree (for something like
simplicity :p). You are traversing it (using infix, postfix or prefix)
to search for a node. You find your required node. You just realized
that you need to know the path from this node back to the root node
(and/or vice versa). Given the following description of the structure
of the tree node that you “cant” change:
struct node{Data data; node *right,*left;};
what will you strategy be to tackle this problem.
To make it more intresting (or maybe just the application of the above
problem) suppose you find the node A and a node B in consecutive
searches. Now what will your strategy be to show a path from A to B.
(not neccesarily from the root of the whole tree, but possibly).

Re: [algogeeks] zig zag
How about this dp solution? Let dp[i][j][k] be the lookup table. It is defined as the longest zigzag sequence in the range i and j. k is either 0 or 1. 0- if the sequence ends with a positive difference, i.e last element is greater than the last to one. 1- if the sequence ends with a negative difference. Now we can define the recursive formula as follows, for(k=i;kj;k++) dp[i][j][0]= max(dp[i][j][0],dp[i][k][1]+dp[k+1][j][0]) dp[i][j][1]= max(dp[i][j][1],dp[i][k][0]+dp[k+1][j][1]) correct me if i am wrong. On Fri, Jan 21, 2011 at 12:48 PM, snehal jain learner@gmail.com wrote: A sequence of numbers is called a zig-zag sequence if the differences between successive numbers strictly alternate between positive and negative. The first difference (if one exists) may be either positive or negative. A sequence with fewer than two elements is trivially a zig-zag sequence. For example, 1,7,4,9,2,5 is a zig-zag sequence because the differences (6,-3,5,-7,3) are alternately positive and negative. In contrast, 1,4,7,2,5 and 1,7,4,5,5 are not zig-zag sequences, the first because its first two differences are positive and the second because its last difference is zero. Given a sequence of integers, sequence, return the length of the longest subsequence of sequence that is a zig-zag sequence. A subsequence is obtained by deleting some number of elements (possibly zero) from the original sequence, leaving the remaining elements in their original order. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Distance in a dictionary
Ok lets define the following functions. movegen()- gives the list of next move given the state. This is basically all the 1 distance words given the current word. heuristic()- this gives the number of non-matching characters of the given word with the goal word. Start from start state and expand. Now always choose the move which gives a lesser heuristic valued state. Stop if you reach the goal.

[algogeeks] sorted array inplace merge
Given an integer array of which both first half and second half are
sorted. Write a function to merge the two parts to create one single
sorted array in place [do not use any extra space].
e.g. If input array is [1,3,6,8,-5,-2,3,8] It should be converted to:
[-5,-2,1,3,3,6,8,8]
i have thought of the following approach
[1,3,6,8,-5,-2,3,8]
||
ptr1ptr2
*ptr1*ptr2
so shift as follows
[ -5,1,3,6,8,-2,3,8]
| |
ptr1 ptr2
[-5,-2,1,3,,6,8,3,8]
| |
ptr1ptr2
[-5,-2,1,3,6,8,3,8]
| |
ptr1 ptr2
[-5,-2,1,3,6,8,3,8]
| |
ptr1 ptr2
[-5,-2,1,3,3,6,8,8]
| |
ptr1 ptr2
[-5,-2,1,3,3,6,8,8]
| |
ptr1 ptr2
{-5,-2,1,3,3,6,8,8]
