What can I do if I'm always getting hung up on thinking questions and have an extremely poor level of construction?

Solve problem 1400-1600 and try to solve fast 5 problem on div 3. Learn dp, graphs, STL, binary search. It's all what you need. Good luck)

          You are right, but he is my classmate, and he is also in the math competition class. But he sometimes goes to cut class.

    i know all of these topics also two pointers segment tree and disjoint sets union,but i cant use them prperly on problems,so should i just keep practising or do youknow another way to get higher your problem solving ability

      Мне лень писать на английском так что буду на русском, переводчик тебе в помощь) DSU и Segtree это слишком сложные алгоритмы для тебя, на твоём уровне нужно знать binary search, two pointer, linear algorithms и решать решать и ещё раз решать задачи

        Ты русский? Зачем я себя мучал,ну все это я уже знаю просто видите ли в кодефорсесе задачи намного сложнее чем в других сайтах,так как там в основном идеи для задач лежат в глубине,то есть надо из какого то факта вывести что то чтобы решить задачу,но так как я очень много решал задач не на кодефорсесе я отвык от таких задач

Not many topics are required however you need decent math skills. So work on that, improve your math intuition and pattern recognition (which is hard yes, but if you do so, you'll definitely reach expert).

Keep practicing till you can solve 3 or more problems in Div.2 contests.
