[13 Feb 2020] Check if a given sequence of moves for a robot is circular or not

Check if a given sequence of moves for a robot is circular or not Link:  https://www.youtube.com/watch?v=f7Zd8hEbCz0 Given a sequence of moves for a robot, check if the sequence is circular or not. A sequence of moves is circular if first and last positions of robot are same. A move can be on of the following. G - Go one unit L - Turn left R - Turn right Input: path[] = "GLGLGLG" Output: Given sequence of moves is circular Input: path[] = "GLLG" Output: Given sequence of moves is circular The idea is to consider the starting position as (0, 0) and direction as East (We can pick any values for these). If after the given sequence of moves, we come back to (0, 0), then given sequence is circular, otherwise not. N | | W -------------- E | | S The move ‘G’ changes either x or y according to following rules. a) If current direction is North, then ‘G’ increments y and doesn’t cha...

C/C++ Complete Program Preparation Memory Layout of C Programs Question 9. Can You Name A Situation Where Joining Threads Should Be Avoided? Answer : A call to join() blocks the caller thread. This is really bad in situations where the caller thread is a main UI thread – because if the UI thread blocks, the application will stop responding to user inputs which will make it seem hanged. Another place where calling join() is not advisable is inside a main game loop. Calling join() can block update and rendering of the game scene and severly impact the user experience (it'll be like watching a You tube video on a dial up internet connection !). https://www.wisdomjobs.com/e-university/c-multithreading-developer-interview-questions.html https://www.wisdomjobs.com/e-university/c-multithreading-developer-interview-questions.html https://www.wisdomjobs.com/e-university/advanced-c-plus-plus-interview-questions.html C++ Preparation             ...
