ferry    ACRush: What do you do when you can’t solve a problem or you don’t know what’s wrong? 
ACRush    ferry: I will try to pass it in practice room. I always do that. 
  
geekru2    ACRush: Do you solve puzzles and mind bending questions to improve your problem solving techniques?

ACRush    kcm1700: The trickiest one, of course. 
  
binarywithme    ACRush: sir what is the best way to learn DP. 
ACRush    binarywithme: TC contest. 
  
[dasha]    ACRush: When u were beginning to compete,did u have any problems? Like low speed of sloving, or maybe some particular method u couldn’t understend for a long time, sth else? If yes, how did u get over that? 
ACRush    [dasha]: USACO is a really good place. Especially for the beginners.

Sarkin    ACRush: Do you use algorithm analyzis when solving a problem to see it’s effeciency? 
ACRush    Sarkin: Yes. the effeciency sometimes is more important than correctness in TC contest. 
  
coder29    ACRush: basically i want 2 to do pratice on DP and greedy types…is TCs’ room are sufficient..? 
ACRush    coder29: A bulk of dp tasks in SRMs. TC’s room is good.

ACRush    rajeshsr: Practice is the way. 
  
Lingmum    ACRush: How can we improve our speed of solving the problems,more problems? 
ACRush    Lingmum: More practice. 
  
stormsky    ACRush: do you often practice TC?and how to practice?

sahiltiwari    ACRush: how many hours you practise per day ? 
ACRush    sahiltiwari: 4-5 
  
MohammadReza    ACRush: What do you do to make your code becomes bugfree although the big size? 
ACRush    MohammadReza: test more tricky cases.(corner cases) 
  
rajeshsr    ACRush: Sorry to be repetitious, But I want to know what is the strategy of practice you employed? U select some random problems from OJs and solve or try to master a particular domain like DP by solving problems based on that or any other thing? 
ACRush    rajeshsr: set problems of past regionals and finals. 
  
puneetkp444    ACRush: Can you suggest some ways to improve problem solving abilities 
ACRush    puneetkp444: practice all kinds of problems. 
  
alft7    ACRush: what do you usually do before a very important competition, practise or something else? 
ACRush    alft7: practice until 3 days before it.
