#if numbers of elements is 4 then multiply the 1st by 3600, multiply the 2nd by 60 and add the 3 first numbers; consider the result as the new 1st element
# while if the number of elements is 3 then multiply the 1st by 60 and add it to the 2nd element; consider the result as the new 1st element
#so that in the end I'm left with 2 columns: time in seconds and number of compilation(s)
