binary notation

Number of python3 (in actual application -- hexadecimal, octal, and binary notation)---------- Python integers can be written in hexadecimal, octal, and binary notation to supplement general decimal notation. Example: >>> 0o1, 0o20, 0o377 # octal (2

There is a string array r = [ABC, Bac, ACB]I only want to retain one of the strings, that is, to delete strings with the same content but different character combinations.     I will introduce you to the single-digit operation technique, which is

Reprinted from:Http://www.cnblogs.com/python27/. Question: enter an integer to determine the number of 1 in the binary representation of the positive number? For example, if the input integer 12 is converted to a binary value of 1100, there are

Two examples of subnettingExample 1: This example divides subnets by the number of subnets, regardless of the number of hosts.A group company has 12 subsidiaries, and each subsidiary has 4 departments. The superior gives a 172.16.0.0/16 network

In- depth understanding of computer System Chapter II study SummaryOur exploration of computer systems begins with learning the computer itself, and it is made up of processors andMemory subsystem. In the core, we need methods to represent the basic

Both int and float are 4-byte, 32-bit representations. Why is the range of float greater than int?Float precision is 6~7 bit. 1.66*10^10 's numerical results are not 166 0000 0000, the larger the error.These problems are caused by the way

A floating-point number is a numeric representation of a number in a given subset of a rational number, which is used to approximate any real numbers in a computer. Specifically, the real number is obtained by multiplying an integer or fixed-point
