Merge sort is similar to the idea of quick sort: Divide the data to be sorted into two parts, continue to recursively merge the two sub-parts, and then combine the two sub-parts that are already ordered, and finally complete the sort. Both the time

1. Signed number and unsigned numberThe signed number is the highest bit ,0 for Positive, and1 for negative .The highest bit of unsigned number is not a sign bit , but a part of a number.1011 1111 0000 1111 1111 0000 1011 1010 If there is a

One, what is alignment, and why to align:1. The memory space in modern computers is divided by byte, theoretically it seems that access to any type of variable can start from any address, but the reality is that when accessing a particular variable,

The Transition property is a shorthand property for setting four transition properties: Property Duration timing-function delay; Transition-property Transition-duration Transition-timing-function Transition-delay

JavaScript variable declaration elevation (hoisting) JavaScript's variable declarations have a hoisting mechanism, and the JavaScript engine, when executed, promotes the declaration of all variables to the front of the current scope .Look at a piece

In most languages of Class C, a block of code enclosed by a pair of curly braces is a scope. But the scope of JavaScript is defined by functions. Variables defined in a function are only visible inside the function, which we call the function scope.1

Directives as the most important part of the ANGULARJS, so the framework itself has a lot of instructions, but in development, these directives often do not meet our needs, so we also need to customize some of the instructions. Directives are one of

Members in a struct can be of different data types, and members are stored sequentially in contiguous memory space in the order in which they are defined. Unlike arrays, the size of a struct is not a simple addition to the size of all members, and

First, arithmetic operationsThere are 34 types of operators in C, including common subtraction operations1. Addition Operation +L can also represent a plus:+5,+90 , except to do addition operations.2. Subtraction operation-L can do subtraction, but
