Given a string consisting only of digits, find the missing number. For instance, given the string 596597598600601602 the missing number is 599. You may assume all the numbers are positive integers and the sequence increases by one at each number except the missing number. The numbers will have no more than six digits and the string will have no more than four hundred characters.

Your task is to write a function to find the missing number in the sequence. If there should no missing number whatsoever, return a value of -1

JSON PARSING ( Print all the data from a Json String).

Input : {'firstname' : 'abc'}

Output : firstname -> abc

Input : {'firstname' : 'abc', 'lastname' : 'Lincoln'}

Output : firstname -> abc lastname -> Lincoln

Input : {'address' : '365 KG', 'lastname' : 'Lincoln'}

Output : address -> 365 KG lastname -> Lincoln

Ideally, you must parse the JSON string into a map data, and then print out the elements of the map. Among other things, it will help print out the data in alphabetical order as well.

An Integer array is given,

Find the combination of number in the array which satisfies the equation: a to the power b= c.

A number should not be repeated in multiple combination.

1. a and b are adjacent no. in the array.c can be any where in the array.

2.No other array or data structure can be used. However modification of current array is possible.

Define a function which will take array as input and generate a output array (a modification of input array).

Example: Input array: 1 2 3 8 5

out put: 2 3 8 0 0

Write a function that will operate on a C-string and convert all instances of "AB" to "C" without using a second string for temporary storage. Use the following function signature:

void translate(char *str)

So for example:

char astring[] = "helloABworld";

translate(astring);

// Now astring holds "helloCworld";

Your function should handle strings of arbitrary length.

The "Island Count" Problem

Given a 2D matrix M, filled with either 0s or 1s, count the number of islands of 1s in M.

An island is a group of adjacent values that are all 1s. Every cell in M can be adjacent to the 4 cells that are next to it on the same row or column.

Explain and code the most efficient solution possible and analyze its runtime complexity.

Example: the matrix below has 6 islands:

0 1 0 1 0

0 0 1 1 1

1 0 0 1 0

0 1 1 0 0

1 0 1 0 1

Count the Mines Problem:

Your program will first read an integer N from stdin.

Then it will then read N lines of N integers separated by spaces.

Each integer in this Grid will be either 1 or 0.

The program then outputs an N x N Grid where each Grid element represents the number of 1's surrounding that element, (excluding the element itself).

For (column, row) = (0, 0), surrounding element indices are (0,1) (1,0) and (1,1).

Similarly for (1,1), surrounding element indices are (0,0) (0,1) (0,2) (1,0) (1,2) (2,0) (2,1) and (2,2).

Constraints:

Your output lines should not have any trailing or leading white space

Maximum Dimension of Grid = 1000 x 1000

Example Input:

"3 0 1 0 0 0 0 1 0 0"

Expected output:

1 0 1

2 2 1

0 1 0

There are three closed doors. Behind two of them there are donkeys, behind the third one there is a Mercedes-Benz. (Your task is to get the Mercedes, not the donkey).

You are asked to choose one of the doors. Once you have chosen, they open one of the remaining two doors with the donkey. Now there are two doors left: one you chose and the other one. To maximize your chance of getting the Mercedes, should you keep your choice or switch to the other door?

Out of three, I able to get something about first 2 but the last one is very difficult for me to understand. Plz explain "object" in arg.:

`"synchronized (object){//write code here}"`

`synchronized (this) { //write code here } synchronized (Myclass.class) { //write code here } synchronized (object) { //write code here }`

Construct two threads in a program and execute them one after another. Write thread writes the data in a buffer and reader thread reads the data of previous thread from the buffer. Before execution of threads, user has to provide the string of 10 words the writer thread reads data from the string and write one word in the buffer. The reader thread reads the word from the buffer and displays it on screen.
