The new format shows exceeded limits with a <code>></code> symbol, for example: <code> > 2000 ms</code> / <code>> 1048576 KiB</code> Behavior for MLE has been changed. In the new judge, execution is forcibly terminated as soon as the memory limit is exceeded. <strong>Depending on the situation on the day of the contest, it may be conducted using the previous judge environment.
