Sum up integer array?
write a boolean method to find out if a number is a power of 2
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.
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.
Design a Data Structure SpecialStack that supports all the stack operations like push(), pop(), isEmpty(), isFull() and an additional operation getMin() which should return minimum element from the SpecialStack. All these operations of SpecialStack must be O(1). To implement SpecialStack, you should only use standard Stack data structure and no other data structure like arrays, list, etc.
int getCount(int[] arr, int num)
find a loop in a list
The hardest question I was hit with was to write a function that takes an integer N and returns an NxN matrix with incrementing integers in a spiral, from outside in.
