I will go against my instinct, disobey my nature and love you forever. Let's summarize the sorting (left over from the last lesson) 1, Stability of sorting (02:56) The same values in the sorting process are sorted by the sorting algorithm, and their relative order remains unchanged. (for the simple basic type array, it is of little use. It do ...

1, Deep and shallow copy Shallow copy: When implementing a string, if you do not copy the string first, a copy constructor will be automatically generated, but it is only a shallow copy. Two string objects point to the same address. When two objects call the destructor, the destructor called by the previous object has released the internal sla ...

Bucket sorting: The sorting under the bucket sorting idea is not based on comparison, and the application range is limited. The data status of the sample needs to meet the bucket division. The following describes the two sorting methods under the bucket sorting idea (1) Count sort (2) cardinality sort Time complexity O(N) Count so ...

Hamiltonian problem and Hamiltonian ring In 1859, the Irish mathematician Hamilton proposed the following game to travel around the world: London, Paris, Moscow and other world-famous cities were marked on the 20 vertices of the regular dodecahedron, and the edges of the regular dodecahedron represent the routes connecting these cities. Can yo ...

Restrict prop to a list of types Using the validator option in the prop definition, you can limit prop to a specific set of values: export default { name: 'Image', props: { src: { type: String, }, style: { type: String, validator: s => ['square', 'rounded'].includes(s) } } }; Copy code The validator ...

preface         Today, I will share with you a very important sorting algorithm among data structures and algorithms. The so-called sorting is to reorder the data elements in ascending and descending order according to the specified keyword size. Sorting is a basic operation of data structures such as linear tables and bin ...

1, Circulation 1.1 cycle Now I have a problem: the program reads in a positive integer with less than 4 bits (including 4 bits), and then outputs the number of bits of this integer. If input 352, output 3. People's way: you can see it with your eyes. We can see that 352 is a three digit number at a glance. The way of computer: what the ...

brief introduction In programming, we often need to perform the same or similar operations. These operations are completed by a piece of code, and the emergence of functions can help us avoid writing this piece of code repeatedly. The function is to abstract a relatively independent function and make it an independent entity. One reason why Py ...
