-> WAP to sort structure objects -> WAP to create mirror image of a tree -> WAP to fetch 2nd biggest element in a array. later extend the same logic to fetch kth biggest element in a array -> implement atoi Now concept questions: -> create a deadlock -> create a memory corruption -> implement a file transfer logic, take care of as many conditions as possible -> how can you speed up, read and write process. Very basic, like how Torrents work, multiple threads can write at multiple locations.
