填坑，汇编递归版

Include masm32rt.inc
.const
	CrLf db 0DH,0AH,0
.data?
	Input db 20 dup (?)
.code
	recursion Proc Uses Ebx Eax Ecx lpStr:dword
		Mov Ebx,lpStr
		.If Byte Ptr [Ebx+1] != NULL
			Mov Al,Byte Ptr [Ebx]
			Xor Ecx,Ecx
			.Repeat
				XChg Al,[Ebx+Ecx]
				Mov Byte Ptr [Ebx],Al
				Inc Ebx
				Invoke recursion,Ebx
				Dec Ebx
				XChg Al,[Ebx+Ecx]
				Mov Byte Ptr [Ebx],Al
				Inc Ecx
			.Until Byte Ptr [Ebx+Ecx] == NULL
		.Else
			Invoke StdOut,Offset Input
			Invoke StdOut,Offset CrLf
		.EndIf
		Ret
	recursion Endp

	Start:
		Invoke ArgClC,1,Offset Input
		Invoke recursion,Offset Input
		Invoke ExitProcess,NULL
	End Start
End
