Pergunta de entrevista da empresa Oracle

Third round. 1. To write C++ code to sort array, or something very similar 2. Two puzzles - Fox and duck puzzle - one is in the middle of a circle and the other cant enter this circle. What is the best path for the animal in the middle to escape? Some square cutting puzzle - I don't remember this, but I suggest going through puzzles in Indiabix or crazyforcode
