Given integer m and n where n is odd, for all mxn matrixes that consist of 0 and 1, find the one that has max count of 1s and meets following conditions:
1. All 0s are connected;
2. All 1s are adjacent to at least one 0 (Adjacent includes diagonal line adjacent, 8 directions);
3. maxtrix[m-1][n/2] = 0.

Example :

Input: m=2, n=3
Output: [[1,1,1],[1,0,1]]

Follow up:
Given another list of 'blocked' points. Matrix will set those points to -1 and you cannot change that. Solve the problem again.

French fishermen have been accused of throwing insults, rocks and smoke bombs at their British rivals in the English Channel in a vicious scrap over scallops.

The clash happened around 12 nautical miles (22km) off the Normandy coast, near the Bay of Seine.

British boats are legally entitled to fish in the scallop-rich area.

Design an email client where you can only send emails to people who are present in your contact list. Build for only the following functionaliy
1) Send/Receive Emails
2) Add/Remove Contacts
3) See Inbox
4) See Sent Mail

Design a distributed LRU Cache.

You are given a set of functions:

int open_port();
opens a serial port and returns 0 if everything ok (or -1 if error)

int read_port(char *buf, int buf_size)
which reads data from a serial port and stores it to 'buf' of size 'buf_size' or blocks until the data is available and returns the number of bytes read (or -1 if error occurred)

void close_port();
closes a serial port connection

Design a class:

class SerialConnection {
public:
     using ByteHook = std::function<void(char)>;

     SerialConnection(ByteHook callback);
....    
};

which should read data from the serial port asynchronously and send it to the callback function ByteHook byte by byte (e.g., for decoding).

Note that if you don't call 'read_port' often enough, the underlying system buffer might get full and some bytes will get lost..

Count maximum number of pair (a, b) possible from an array so that a is less than equal to 2*b. Also tell number of unpaired element left.
So for Input
1, 3, 5, 6, 7
ans = 2 1

An array is special if it contains special elements. A special element is an element which can be represented by the sum of two numbers where one number is reverse of other. Like Array is {22, 121} . Here 22 = 11 + 11 and 121 = 92 + 29. Hence both elements are special. The input array is an array of strings. Output number of special elements in the array.

Two players and are playing a game.They are given binary numbers as input. Each binary number is represented as a string of characters '0' or '1'. The string always ends at '1'. In one move each player decides a bit position . Then he visits all the numbers and if their bit at that position is '1' then he changes it to '0'. It is mandatory to flip(change '1' to '0') bit of atleast one number in each move. The player who is unable to make a move loses. Player begins the game.

Input
First line contains a number as input. Next lines contain a binary string each.

Output
Print A if player A wins , B otherwise. In the next line print the move number of the last move of the winning player.

Remove 3 or more consecutive characters from a string, repeat until there are no more.

eg.

ABCCCCBBA => ABBBA => AA
