Give four points, determine is it is a square, rectangle or none of the above.

Given list of nodes of a tree, find the root of the tree. Nodes in the list are not in any particular order.
If all nodes in the tree are not given, return null



A
B C
D E F



F E A << input
A << output

public class Node
{
public Node[] Children;
public Node Right;
}
 Each node represents an element of a tree and specifies a list of immediate children.
 The 'Children' property lists all children (in order) but the 'Right' property is set to null.
Suppose you are given the root of a fully populated tree (i.e. a Node called RootNode). Write code to set the 'Right' property so that each node is linked to its right sibling.

Given the following xml file, and input containing the root node as well as the attribute name,

return an IEnumerable<string> of the values. The candidates should use xpath to solve the problem



ex input: xmlNode = employees, attrName = “name”

ex output: Yuri, Alex as an IEnumerable of strings

*/

<root>

<employees>

<employee>

<id>1</id>

<name>Yuri</name>

</employee>

<employee>

<id>2</id>

<name>Alex</name>

</employee>



</employees>

</root>

Write a function that determines whether a two dimensional array contains duplicate values within k indices of each other

The first line of input will be a number indicating how many rows are in the matrix. This will be followed by lines of input one for each row of the matrix each row will contain the same number of columns with each column separated by a space. Following the matrix will be a single line of input containing a number indicating the k value.

Output should be ‘YES’ or ‘NO’
example:
4
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
3

Output: No

Given a tree and a number N, construct another tree such that each node of the tree has either 0 or N elements,except for one node which has between 0 to N elements.Only other constraint is that ancestry is preserved in the new tree.

Design a game like angry birds

Check if the given cordinates on a map correspond to the correct address (where address or cordinates are provided in a tab separated file)

Reverse string except spaces. A string has mix of alphabets and spaces. Your task is to reverse the string, but preserve the positions of spaces. For example, reverse of " a if" is " f ia".

difference between hashtable and hashmap in C#?
when to use hashtable, list, hashmap and dictionary.

Given a string, find whether it has any permutation of another string. For example, given "abcdefg" and "ba", it shuold return true, because "abcdefg" has substring "ab", which is a permutation of "ba".
