(Translate from Assembly to C) Rewrite the foo function in C. Write the function's prototype and all code contained within. Don't forget about arguments and local variable definitions:

push rbp mov rbp,rsp mov QWORD PTR [rbp-0x18],rdi mov QWORD PTR [rbp-0x8],0x0 jmp 400733 mov rax,QWORD PTR [rbp-0x18] lea rdx,[rax-0x1] mov QWORD PTR [rbp-0x18],rdx add QWORD PTR [rbp-0x8],rax cmp QWORD PTR [rbp-0x18],0x0 jne 400723 mov rax,QWORD PTR [rbp-0x8] pop rbp ret
