why is one program slower than the other what is time limit of program how many gb of memory does a program use how fast is the computer program running is it better to compare performance of two programs on $n$ inputs? comparing the running time and memory speed how to test if a program is faster in memory how to compare two programs running at different speed how to compare performance of two programs difference between performance test and compared program why is memory limit exceeded comparing performance of two programs on $n$ how to compare time between two programs when do you record running time of a program what is the difference between a program and a program how can i compare performance of two program which program is faster why is a time limit overwritten? comparing the running time of a program why does each program has more memory
