There are two model: 1) Acoustic model

2) Language model

We have a dictionary full of trained voice which will be recognized. Can anyone tell me in which model the recognition happens?

Thanks.

What Rank one should obtain to get invitation for interview?

I could not understand the complexity of this series. N/1+N/2+N/3+N/4+.....+N/N.

cAN ANYONE EXPLAIN ME? tHANKS.

Please, anyone help me on solving the segment tree part of the following problem: http://codeforces.com/contest/589/problem/G

I can handle the Binary Search part.. But the Segment tree part is very hard to me.

Anyone can Give me Some problems on Articulation Points on Codeforces?

Thanks.

*I am very much trying to understand iterative dp but not getting it comfortable. I've done many paperwork.* *For example:* *For the following problem I can design a solution which run on O(n*k*S) which is not efficient.* *Can you help me on this that how to understand, find out solution in iterative dp?* *I can design recursive dp bt can't transform it in iterative dp.*

**Problem: LightOj-1145**

You have N dices; each of them has K faces numbered from 1 to K. Now you have arranged the N dices in a line. You can rotate/flip any dice if you want. How many ways you can set the top faces such that the summation of all the top faces equals S?

Now you are given N, K, S; you have to calculate the total number of ways. **Input**

Input starts with an integer T (≤ 25), denoting the number of test cases.

Each case contains three integers: N (1 ≤ N ≤ 1000), K (1 ≤ K ≤ 1000) and S (0 ≤ S ≤ 15000). **Output**

For each case print the case number and the result modulo 100000007.

**Sample Input:**

5

1 6 3

2 9 8

500 6 1000

800 800 10000

2 100 10

**Sample Output:**

Case 1: 1

Case 2: 7

Case 3: 57286574

Case 4: 72413502

Case 5: 9

Can I get some problems which can be solved by dijkstra on codeforces?

Hi! I've seen many codes where 1e-11 (like this) is used to compare two double numbers. Why we use this? what it we do not use this?

Thanks in advance.

**I want to know, is it unnecessary to spend too much times for a particular problem although I am figuring out different inefficient solution. What should I do now?**

I have tried this problem very much but failed to solve this. I have looked on many codes but failed to understand. Since this problem has no editorial so I can't forward anymore.

Please anyone give me some explanation on this problem. Link: http://codeforces.com/contest/257/problem/C

Thanks.

Here is a problem I had been trying in Light Oj.

Problem link: http://paste.ubuntu.com/11060539/ (Since Light OJ need a user id to access)

I could solve it recursively: My solution: http://paste.ubuntu.com/11060583/

Now I want to solve it iteratively. But I am failing to do it. Please explain me how I can do this in iterative process in two dimension array like, int dp[102][10002]:: dp[n][k];

In some code I see to act like this: for(int i=0;i<=n;i++) dp[i][0]=1;

why does it fill,fill dp[i][0]?

Please I need to learn this . I am trying but failing.

Thanks in advance.
