1. Sort array with ones and zeros. This was the most "complicated" part. 2. Complexity of insert/delete/find in double linked list, binary tree. Complexity of sort of array of numbers, of sorted array of numbers. 3. Questions like what order ctors/dtors work. 4. Some crap with 2 classes having static shared ptr for kernel object, where kernel was class poorly written. Like what's wrong with the code was the question. 5. int x; int &j; j=x; What's wrong? Reference should be assigned to a variable when declared actually. Other questions very primitive.
