We have briefly introduced the binary number system. We will not go into detail here. The computer can only recognize binary systems. We know that a computer is composed of multiple electronic components, and the electronic components
Description:Input an integer and output the value in binary format. The negative number is indicated by the complement code.Input:The input may contain multiple test examples.For each input file, enter an integer T in the first line, which indicates
Exploration of bit operations and exploration of operationsPreface
As the blogger keeps writing articles during the idle time of his work, only the exploration of bit operations here [begin.

A: What is A constant?
The value of the program cannot be changed during execution.
B: Classification of constants in Java
Nominal value constant
Introduction Big-endian and Little-endian Big-endian, Little-endian are related to multibyte-type data, such as the Int,short,long type, but not to single-byte data byte. The Big-endian is the low byte emitted at the high address of the memory
In binary, 1 has an odd or even number.We can use the following code to calculate the parity of the number of 1 in a 32-bit integer binary. When the binary representation of input data contains an even number of 1, the program outputs 0, if there
Binary OperatorsBecause data in the computer is in binary format, Java provides binary operators for direct operations. This is the bitwise operators and shift operators to be explained below.Binary operators can be used to operate numbers directly

Char and unsigned char are unsignedBoth are used words as words that are indistinguishable, but when integers are used differently:Char integer range is-128

1. Representation Method:
In Java, the binary number is represented by a complement. The highest bit is the symbol bit, the positive number is 0, and the negative number is 1. The following
