冪集 | Power Set
一個集合的冪集是它所有子集的集合。寫一個函數(shù)，給定一個集合，生成它的冪集。
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);

使用GORM和GIN在Golang中實現(xiàn)簡單分頁功能
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/MySQL go get github.com/gin-gonic/gin go get github.com/jinzhu/gorm
目錄結(jié)構(gòu)
- /first-api - /Config - /Controllers - /Model - /Routes - go.mod - go.sum - main.go
核心分頁部分。
config.go: DB實例
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
