I observed lot of good coders could read and understand questions within seconds. I would have solved over 186 problems in leetcode(144 easy, 44 med, 2 hard), and over 200 problems on other sites in different accounts(including contests), still i can't comprehend questions faster. Even with some amount of practice, I find that, I am extremely slow in understanding simpler sentence. What is the technique which allows coder to read extremely fast and How one can one improve the speed of reading and understanding a problem?
