[algogeeks] Additive sequence
Hi, I dont remember the question text exactly but the following should convey it well The question: A number is said to be an additive number if it has the following format: 3268126844 : 32 6812 6844 : 32 + 6812 = 6844 123581321 : 1 2 3 5 8 13 21 : 1+2 = 3 , 2+3 = 5 , 3+5=8, 5+8 = 13, 8+13 -21 347 : 3 4 7 : 3+4=7 122331234346746 : 122 3312 3434 6746 : 122 + 3312 = 3434 , 3312+3434 = 6746 If the number is broken down into non zero ( 303 : 3+0 = 3 is not additive ) segments,and when these segments are taken in groups of consecutive 3 ,(so two digit or single digit inputs wont qualify), the first two should add up to the third number, such a number is called as an additive number. Given a range of numbers, print all the numbers which are additive in the sequence.

Re: [algogeeks] subset of an array
the simplest code could be for this question is
void printAllSubsetSum(int ar[], int n, int x)
{
for (i = 0; i (1n); i++)
{
int sum = 0;
for (j = 0; j n; j++)
{
if ( (1 j) i) sum += ar[j];
}
if (sum == x)
{
for (j = 0; j n; j++)
{
if ( (1 j) i) printf(%d , ar[j]);
}
printf(\n);
}
}
}
Time complexity O(2^n)
this can be solved using DP in O(n * given number);

Re: [algogeeks] Give Algo to do this in O(n)
Counting Sort is really a Bad option for this Problem as range is not given yes range can be find in single traversal but think if largest element is 10^9 and size of the array is just about 10^3 Counting Sort = O(10^9) Simple Sorting = O(10^4) Counting sort will perform bad in this case both in terms of Space Requirements and Time On Mon, Oct 10, 2011 at 11:25 PM, snehi jain snehijai...@gmail.com wrote: ankur : i wont say its the best way, but it can be used in one traversal the range can be determined and then count sort can be applied.

[algogeeks] Re: remove duplicate words from a string
a) 1. could split the string using a regexp (into an array) in which you define a word -- is hi. the same as hi, and hi ? 2. then perform a unique operation on the array (some languages have this built in) to remove duplicates 3. recombine array elements into string by joining with a space, for example, depending on how you split it in the first step b) Perhaps another way, in-place, could be to check the string, one word (again define this) at a time, storing each word in a hash. If the hash already contains the word, replace this occurrence with spaces or null bytes. Finally compact the string (remove all null bytes, or turn all extra spaces into one space, etc). icy` On Oct 10, 3:08 pm, sunny agrawal sunny816.i...@gmail.com wrote: Trie will take too much space..

Re: [algogeeks] remove duplicate words from a string
@Sunny..How do u intend to store them in a Tree ? Can you explain ? In a trie u first insert the first word ..take the second word..If its not present in the trie u insert it else remove it from original string .Alternatively u store the elements in a trie in the initial string and terminate it with '\0' and return it . In the worst case trie will take O(n) space where n is the no of letters in the string . and Traversal and creation and search too will take O(n). How abt Balanced Binary Tree ?

Re: [algogeeks] Find the later version
divide the string in middle and first compare the left sub-string(as they are MSB)...if they match then compare the right sub-string (iteratively) if the left substring doesn't match then compare iteratively by dividing again. i think this would give complexity in lgn.

[algogeeks] Re: Find the later version
@Karen: It is more complicated than scanning character by character. E.g., 1.10.3 is older than 1.9.7. I think you need to parse the numbers between the dots and compare them one by one. Thus, in the above example, 1 compares equal to 1, so you keep scanning. Then 10 compares greater than 9 so the first string is number of the newer version. I did this many years ago in a csh install script for a unix product.
