translate the "cppFunction" into "asmFunction" and enter your assembler code in "AssemblerFunction.asm", do not change the Main.cpp. You can use the newest Visual Studio project, then you upload the whole project,

but you still cannot change the Main.cpp file. This is an easy Leetcode problem (#121), without any complicated data structures, so it should not be a problem. Everything is set up; you only enter the assembler code.
