i am new here … just 3 months old. i felt some things inconvenient.
i suggest following …
like Google Code Jam … if there are levels for each question, then we will get to know if our approach is correct or not in small input level… then we can go for next level.
i work on the editor directly… when i get errors … i have to go to my submissions and copy my code and modify and again submit… instead if i get errors and solution on same page and if i have edit option then it will be much appreciated.
Hope to get some reply …
