char *a = "hello"; char b[] = "hello"; char *c = malloc(12); What do these do, what's the difference in where the memory is stored?
1) Find the intersection of two arrays as a set. 2) Find the mirror or a binary tree. 3) Find the first non unique character in a stream of potentially infinite data.
Algorithm runtime analysis: What's the complexity of computing the fibonacci numbers?
Implement a queue class.
The chessboard problem. I first mentioned BFS and use of a Queue but the interviewer kept asking about some data structure with less memory that I could extract due to the simple structure of the graph. I did not understand what he meant. I eventually mentioned DFS and proved it works uses less memory. The cache problem took a long time. I kind of though I failed it at some point. I had no prior knowledge of the topic since I am not a CS guy. I eventually, used an array to store the access time to different items and O(n) search through it to find the least frequently used one. The interviewer did not raise the complexity. He wanted me to write code on a paper (which is hard, esp. in C).
Copy a block of memory from source to destination. You need to consider the overlapping cases. Yet I don't think copy from behind will solve the problem. Because the memory may overlap at the beginning. So a pre-check of overlapping region is necessary. In my view, for a typical copy operation the source should not be overwritten, but the answer allows for that. I was pretty confused...
