- Geetha April 19, 2016| Flag | PURGE 0 Answers Simultaneous channels
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?
- viijay April 05, 2016| Flag | PURGE 0 Answers Test Cases During The Whiteboard Interview
In the first cracking the coding interview video Ms. McDowell talks about candidates that begin by writing test cases. How would one go about this? For example, the derivative problem would you create a list of Terms, pass it into derivative(), and write the expected solution before even writing the code? I'm thinking something along the lines of derivative([(10,50),(10,0)]) -> [(500,49), (0,0)], is this what she means?

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 0 Answers I want to run a function that does that automatically for me until the condition is complete (condition is some update statement)
if i have 2000 records and exit when condition should be counter<500;
- sona4144 February 11, 2016
so if i have 2000 records so counter will be 2000/500 =4
loop will execute for 4 times
update statement should consist of
update tablename set counter=1 where rownum<500
this process continues until the update condition is met| Flag | PURGE 0 Answers Maximum number in array after M operations
Given an array numbered from 1 to N, you need to perform M operations. Each operation is described by 3 values a, b and k. Now, k is added for the range of values starting from index 'a' and ending at index 'b' in the given array. Now, After M operations, you have to calculate the maximum of the values in the array.
- apurohit.in January 19, 2016
Initialize the array to '0' before starting to perform M operations.
Consider the number of elements (N) = 5
Number of operations to perform (M) = 4
When M=1,
a=1, b=2, k=100
When M=2,
a=2, b=5, k=100
When M=3,
a=3, b=4, k=100
Initially the array is 0 0 0 0 0
First operation 100 100 0 0 0
Second operation 100 200 100 100 100
Third operation 100 200 200 200 100

Hey guys,
- qiangyuzeng December 29, 2015
I had a 30 minute phone screen interview with Microsoft on 12/15/2015, the week before Winter break. It was a Tuesday. I still haven't heard back from the recruiter, although I have sent a follow up email.
Do you think they have not responded yet simply because it is the holidays? They were interviewing all the way to 12/18/2015.
Thanks
