For Linux: 1) if you change the code, you can use the function "clock" or "getrusage". Clock gives you a number proportional to the used processor time. Divide it by CLOCKS_PER_SEC to get seconds :-). getrusage returns also many additional informations, like the actual used memory, ... 2) Without changing the code, you can use the PROGRAM "time" (not the shell-builtin). On Debian it's installed as /usr/bin/time. Executing /usr/bin/time -v ./yourprogramm gives you also full statistics, including maximal memory consumption HTH, Axel -- You received this message because you are subscribed to the Google Groups "google-codejam" group.
