Yes. That’s a good catch. It is not considered as a white wall, as we did not focus on all the substrings of sizes divisible by 3 but just took only one substring of size 6 for our explanation to show equal number of R, G, B. In the further example, you will find it clear how we need to take all the substrings of sizes divisible by 3 and move forward. Please watch it for a better clarity.

Hey! You can try to approach the Simultaneous robots problem with the following hints: 1. If you don't have the two robots in the picture, how would you approach the problem for only one robot? 2. If you know the path of the first robot, then is there any way such that you can make the second robot not follow the same path? 3. If your both robots are having distinct paths, then you can guarantee that both the paths will be same? 4. If there existed only 1 distinct path, then what do you think the second robot will do such that it doesn't land up in the first robot's path at the same point of time, rather maybe later than the first robot? Try the following test case for additional clarity. 2 4 4 ..#. .##. .... .#.. 5 4 .### .### ...# ##.# ##.. Expected Output: 8 -1

Be consistent with your practice. Participate in every contest, even if you're not fully prepared. Focus on accuracy-solve at least one problem perfectly. After contests, upsolve the problems you couldn't solve. Strengthen your basics in algorithms and data structures, and gradually tackle harder problems. Keep practicing regularly, and your rating will improve!

We can do that as well, but if you notice, the size of the array is very small, so we simply sorted it. If the constraints were larger, we would have used your approach.

hey.. I am beginner in CP ....is sir makes only 3,4 questions video on each time?

If you are encountering a runtime error while using a stack, I recommend reviewing your code thoroughly. The issue might be related to stack operations, such as attempting to pop or peek from an empty stack or exceeding the stack's limits. For a more accurate assessment, could you please share your code? This will help in identifying the exact cause of the error and provide you with a precise solution.

Hello! If the salary could be the key to your success, we'd happily share it! But it’s really the knowledge and experience that we bring to help the students grow is what counts the most.
