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 an array of values, how do you check if there is a combination of them that add up to an integer, n.
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.
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
write a function that receives a dictionary and a string and return true if the string is built of exactly two words in the dictionary
I have superclass A and subclass B of superclass A. B overrides a function foo() in A. I have an instance of class B. How do I call foo() but using class A's version
What sort would you use if you had a large data set on disk and a small amount of ram to work with?
Difficult to answer in short and first time attempt.
find a way to separate money into n parts. For example, if total money is 121, find a way to separate 121 into 4 closest parts and the solution would be an array with elements 30, 30, 30, 31
Not difficult. It is like why can not compare two strings. And how to compare one object which initialed as a string with string. The coding quesition is to find the kth in two sorted arrays.
