First I was asked a few basic design questions, like how I would design an online chat system with separate room. Then I was asked why I've chosen some of of the technologies that I have worked with.I was asked a standard question about manipulating an array. The input array was sorted integers, and I was asked how to square all the elements and keep it sorted.
Given a root to a binary tree where each node holds an integer. Write a method that returns the sum of all the integers in the tree.
Given an array of values, how do you check if there is a combination of them that add up to an integer, n.

Populate an array of numbers from 1 to N (inclusive). Given two numbers, p and q , if a number in the array is divisible by p print OUT, if a number is divisible by q print THINK. If number is divisible by both p and q, print OUTTHINK. Otherwise, print the number.
4.Write a C/C++ program to print the pattern for the given value N. For example N=5 55555 45555 43555 43255 43215 54321
