1. What is a virtual? 2. If class has virtual function, what happens in compile time and in run time? 3. What is a polymorphism? 4. Write the function that gets array of chars and returns number of elements with 3 bits ON, performance is important. 5. Write the function that draws a line from x1,y1 to x2,y2 6. You have very long function with many return statements. You have to determine how much time it runs.
1- Given an array of integers, positive and negative. find an interval in that array, whose elements constitutes the maximum sum
Given an integer write a function that converts the input into a linkedList where each node corresponds to a number of the integer. Eg: 25697 == 2 -> 5 -> 6 -> 9 -> 7 Then write a function that takes 2 linkedList, add the corresponding integers and return a third list with the result.
Write a function that takes an input string, consisting of several words separated by spaces, and print out each word reversed, keeping the same order within the string.
Sum up integer array?
write a boolean method to find out if a number is a power of 2
int getCount(int[] arr, int num)
How would you reverse the words in a string?
Recursively reverse a singly linked list.
