There were 2 questions time limit 90 mins.
1. A person wants to go from origin to a particular location, he can move in only 4 directions(i.e East, West, North, South) but his friend gave him a long route, help a person to find minimum Moves so that he can reach to the destination.
Input – NESNWES
Output – E
You need to print the lexicographically sorted string. Assume the string will have only ‘E’ ‘N’ ‘S’ ‘W’ characters.
E.g – SSSNEEEW
output – EESS
2. A sender will send a binary string to a receiver meanwhile he encrypt the digits. You are given a encrypted form of string. Now, the receiver needs to decode the string, and while decoding there were 2 approaches.
First, receiver will start with first character as 0; S[0] = 0, P[1] = S[1] + S[0], P[2] = S[2] + S[1] + S[0] and so on.
Second, Receiver will start with first character as 1; S[0] = 1, P[1] = S[1] + S[0], P[2] = S[2] + S[1] + S[0] and so on.
You need to print both the strings, after evaluation from both first and second technique. If any string will contain other that binary numbers you need to print NONE.

Round 2(Machine Coding Round):
There was only one question, time limit 45mins
Q1. Word Wrap problem with few conditions, even i didnt remember much conditions here are some conditions.
i) there can be maximum of X characters in a single line.
ii) there can be maximum of Y number of spaces in the end of the each single line.
iii) if a string length is big enough, so that it cannot be printed in single line, use ‘-’ in the end of the line and print string further in the different line.
also there should not be ‘–’ consecutively in the end, if the string contains already ‘-’ in the end dont put ‘-’ character.
E.g. flip-kart and if x = 5 so it should be ->
flip-
kart
iv) the string should not start with these characters(‘.’ , ‘,’ ‘ ‘)
v) the cost value should be minimum, there can not be multiple answer for a single string.
Eg. This is a flipkart online programming test.
x = 10 Y = 3
Output
This is a
flipkart
online pr-
ogramming
test.

and there are many order item to be placed at different location. There can be offers on items).
After explaining he asked me what tables would you like to used for online shopping like flipkart. He asked the the primary keys for every table and foreign key if there are any.
He then asked me about mapping of these keys and what type of mapping to be used here(one to one, many to many or many to one).
Then he asked me about my Codechef and spoj rating. Then he asked me 3 coding questions:
1 – http://www.codechef.com/JULY14/problems/SGARDEN/
