1.yes it’s right question etiquette is must for every employee. TLE error so the input and output to get desired output. but TLE check the error.
2.right strategy for problem solving to understand what is exactly problem, check the optimization for problem, i don’t using any tools like “problematic”. yes i will try get solve the problem by my self.
3.no i have first time to visit this type website.
4.first i will try check the problem, which type of error, then i will try find the solution in code.
5.i will try to inherit the appropriate algorithms. then i will write code for import the algorithm. and for the non-native file then using filter ,no need for copy the algorithm.
6.before start programming, i will check observed the problem how i will solve short with fixed the solution for this problem. enormous input divide in section.
