We often look at the time or space complexity of an algorithm. If we have enough time or space, the algorithm does not need it. Unfortunately, this condition does not exist, in some cases, we do not need to consider one of them. The"Cache", Which is

Processing of internal data types is as follows: global variables and arrays are allocated to data segments before the main function is executed, and the memory is reclaimed by the system after the program ends; local static variables and arrays are
