# Verdict Execution time Memory Grader output
1 Correct 13 ms 888 KB Output is correct
2 Correct 18 ms 1020 KB Output is correct
3 Correct 31 ms 1020 KB Output is correct
4 Runtime error 697 ms 33792 KB Memory limit exceeded: We have a known bug that the memory usage is measured incorrectly (possibly because of Meltdown/Spectre patch), so your solution may be correct. Please submit again. Sorry for the inconvenience.
5 Runtime error 159 ms 33792 KB Execution killed with signal 9 (could be triggered by violating memory limits)
6 Runtime error 210 ms 33792 KB Execution killed with signal 9 (could be triggered by violating memory limits)
