it can be done with O(N * S) time complexity. where N = number of digits S = sum intilize : input[1][j]=0 1<=j <= S input[j][0]=1 0<=j<=N now fill table using following recurrence :- input[i][j] = input[i-1][j] or input[i-1][j-input[i]]; now after creating table...check if input[N][S] == 1 if no then sum cannot be created or if yes , find all combination recursively by first not considering input[i] as part of the subset then considering input[i] as a part of the subset.

Re: [algogeeks] suggest algo
@shashank: sorting the hashed values is more intensive than using the heap with size K.

Re: [algogeeks] suggest algo
@Shashank: i not sure if splay tree would always return k most frequent elements . if we want to find k most frequent elements then doing level order traversal and finding first k elements may not return k most frequent elements bcoz say if number 5 comes for the 1st time , now 5 will be the root of the tree now if we do level order traversal it print first k elements it will include number 5 which has frequency of 1.

Re: [algogeeks] suggest algo
we can use hashtable to maintain count of each number coming from the file. now make a MIN heap of size K now every time a count is updated in the hastable , compare it with the root of the Min heap. if root of heap is smaller then replace it with new greater count and then heapify again. In the end you will be having k most frequent numbers.

One approach could be using the file. Say x = 50 %, so every alternate run, the output should be true. 1. First run, store 0.5 in the file 2. Second run, add 0.5 to the previous value 3. Check if the sum is 1.d where 0 <= d < 1, return true and store 0.d in the file We can extend the same logic for any value of x. -- Pankaj On Wed, Nov 30, 2011 at 12:45 PM, atul anand wrote: > @nitin : as mentioned in the subject , its for Apple > > BTW @siddharth , i did not understand your question . little more > explanation please. > > On Mon, Nov 28, 2011 at 7:14 PM, Nitin Garg wrote: > >> Please clarify.
