Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... + 1/n ., Even number
First, write a function whose n is an even number:
Def peven (n): s = 0.0 for I in range (2, n + 1.0): s + =/I print 'value:', s
Write another function with n as an odd number:

JavaScript has a total of 4 invocation patterns: The function invocation pattern, the method invocation pattern, the constructor invocation pattern, and the indirect invocation pattern. "1" function call Mode when a function is not a property of an object, it is called as a function. For a normal function call, the return value of the function is the value of the

Csapp, the third edition of "in-depth understanding of computer systems: A programmer's Perspective", is a good book, but it needs to be quite basic in reading. Moreover, some of the expressions are not straightforward.For example, the No. 463 page mentions why the assembler sets the initial value of the reference in the call instruction to-4 (for 32-bit systems). Explained vague later. In conjunction with

For simplicity and clarity, mini shell only implements two internal commands:1. CD is used to switch directories. It is similar to the command CD we are familiar with, except that there are not so many additional functions.2. Quit is used to exit the mini shell.

name, one is to add 1 to the internal reference counter (REF), and the other is to release (minus 1). When the counter is reduced to 0, it is the opportunity to release. It looks complicated, but there is no way, because it is introducing the principle. In fact, it is relatively simple to write programs. Please observe the following principles:1. Do not call addref () after starting the component to obtain an interface pointer (). Because the system
