Hi Gayle,
- orsitom17 June 09, 2016
I really like your book CTCI, in the six addition I think you could add to the page 68 example involving the quadratic formula, the only slightly optimized version that solves for d need to check for negative numbers before getting the cube root of a**3+b**3-c**3, and the code should also check to see if d exceeds the range of numbers checked , 1000 in your case.
Thanks,

given 2 strings A and B. generate all possible solutions when B is merged in A.
- JerryGoyal May 22, 2016
Ex: A = "hey"
B: "sam"
then solutions are :
heysam,hseaym,hesaym,sahemy etc.
notice that order should be the same for both of strings while merging.| Flag | PURGE - 0 Answers Find shortest path from set of points
Input: set of coordinates = [P1,P2,...,Pi,.....Pj,....Pn]
- prince May 13, 2016
P denote Point(x,y)
Start point is any of set of coordinates like Pi
simily end point is also any of set of coordinates like Pj.
Find the shortest path with set of points between start and end points.
Let us have a simple example
Set of coordinates :
P4 P5 P6
P1 P2 P3 P7 P8 P9 P11 P12 P13
P10
Start Point: P2
End Points: p12
Output: P2,P3, P7,P8,P9,P11,P12| Flag | PURGE - 0 Answers lucky numbers

Anyone preparing for Facebook interview. I have an interview in exactly 2.5 weeks. I feel bit nervous. If anyone willing to do online study with me for the same? Data structures and Algorithms programming practice? This is for Android dev interview but they said interview would be more like Computer science interview. Any help is much appreciated. Thanks

There are two separate infinite sources of data. Data is arriving simultaneously into our system as two streams via two channels: Channel 1 and Channel 2.
- Coding Panda April 18, 2016
The data could be of three types: R, G and B.
Each data element should have two properties: channelNumber and uniqueID.
These three types of Data are arriving in a random sequence on the two channels.
Write a program which creates pairs of "same types" arriving on two channels in their "order of arrival".
For example, if a sample sequence is as follows:
Channel 1: R1_1 R1_2 R1_3 B1_4 B1_8 G1_5
Channel 2: B2_6 B2_8 R2_9 G2_10 B2_7 R2_20
Then the expected output is:
(R1_1, R2_9) (B1_4, B2_6) (B1_8, B2_8) (G1_5, G2_10) (R1_2, R2_20)| Flag | PURGE - 0 Answers Email response after On-Site interview
Hi, I recently interviewed with Amazon on-site and had an email response from a recruiter (first time hearing from that recruiter) saying they want to call in two days to discuss next steps. Doesn't say if it is an offer, neither does it say it is a rejection. Any ideas? Ever happen to anyone else?

Write a echo TCP client, connect the server interviewer provided and read metric from it.
- max.linweihs March 29, 2016
(You write a client, they provide you server, you just read response from server thats all)
Two request types you can send to server.
1. STATUS
2. Throttle <number>
For example, you send a "STATUS" request to server and server respond back with
<num1> <num2>
0.0 0.0
num1 is your pressure on the paddle
num2 is your current speed
Status
>> 0.0 0.0 (means your current pressure is 0 and speed is 0)
Throttle 50.1
Status
>> 50.1 3.75
Status
>> 50.1 15.98
You can see the speed is increasing, its like driving car. The goal is to how to reach a constant target speed for example like 30| Flag | PURGE - 0 Answers Greedy & dynamic approach
I was recently asked this question in aptitute test:
- pratz2961 March 24, 2016
Write a code to maximize the given expresion having +,- using greedy approach in O(n) and dynamic approach in O(n3).
For dynamic approach i thought we can make use of matrix chain multiplication.
I would like to know if any one has a better approach or code to solve this.| Flag | PURGE
