Starting from SRM 600 TopCoder will be switching to custom time and memory limit settings per problem. We’ve added a separate section “Limits” to the problem statement where both time and memory limits are specified.
Despite that we are able to use any limits, we intend to keep having the same settings for almost all problems as it’s done now. The settings will be 2 seconds and 256 megabytes. Other settings will be used only if the problem requires it and can’t be done with the new default settings. The statement of any such problem will start with a non-standard limits warning message.
All old problems will continue having 2 seconds and 64 megabytes.
