Is there any Platform where i can run my solution to past ICPC ,IOI ,problems???

Although ,we are given test data files (input and output) , but how to execute them on my system to verify it.

Even bigger problem is downloading those test files , for eg. ICPC 2019 problems have i/o file of around 400 MB. Which is very difficult to download such large file for just one contest.

Please , suggest me if there is any alternative way and also how can i run input output file on my system (geany compiler in linux).
