本篇内容主要讲解"如何使用startup架构",感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习"如何使用startup架构"吧!

每天学点算法

幂集 | Power Set

一个集合的幂集是它所有子集的集合。写一个函数,给定一个集合,生成它的幂集。

The power set of a set is the set of all its subsets. Write a function that, given a set, generates its power set.

For example, given the set {1, 2, 3}, it should return {{}, {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3}}.

# https://tutorialspoint.dev/algorithm/mathematical-algorithms/power-set# python3 program for power set   import math;   def printPowerSet(set,set_size):           # set_size of power set of a set     # with set_size n is (2**n -1)     pow_set_size = (int) (math.pow(2, set_size));     counter = 0;     j = 0;           # Run from counter 000..0 to 111..1     for counter in range(0, pow_set_size):         for j in range(0, set_size):                           # Check if jth bit in the              # counter is set If set then              # print jth element from set              if((counter & (1 << j)) > 0):                 print(set[j], end = "");         print("");   # Driver program to test printPowerSet set = ['a', 'b', 'c']; printPowerSet(set, 3);   # This code is contributed by mits.

每天学点Golang

使用GORM和GIN在Golang中实现简单分页功能

原文:Implement Pagination In Golang Using GORM and GIN

The packages you need to install in our project is:

go get github.com/go-sql-driver/mysqlgo get github.com/gin-gonic/gingo get github.com/jinzhu/gorm

目录结构

- /first-api        - /Config  - /Controllers  - /Model  - /Routes  - go.mod  - go.sum  - main.go

核心分页部分。

  • config.go: DB实例

  • repo.go

import (        "first/src/first-api/Config"        models "first/src/first-api/Model")func GetAllUsers(user *models.User, pagination *models.Pagination) (*[]models.User, error) {        var users []models.User        offset := (pagination.Page - 1) * pagination.Limit        queryBuider := Config.DB.Limit(pagination.Limit).Offset(offset).Order(pagination.Sort)        result := queryBuider.Model(&models.User{}).Where(user).Find(&users)        if result.Error != nil {                msg := result.Error                return nil, msg        }        return &users, nil}
