15. Go - Structs

Struct is an aggregate data type that aggregates together values of different types.


Creating struct:

type myStruct struct {
    name string
    age int
}


Creating a variable using a type struct:

// Using composite literal TYPE{values} to create.

    personA := myStruct {
        name: "BOB",
        age: 32,
    }


Accessing fields in a struct:

// Using dot notation

    fmt.Println(personA.age,personA.name)


Sample Code:

package main

import "fmt"

// Human Struct
type humanA struct {
    gender string
    age    int
    weight float64
}

//
func (a *humanA) printdetail() {
    fmt.Printf("Name: Peter\nGender: %s\nAge: %d\nWeight: %g", a.gender, a.age, a.weight)
}

func main() {
    var peter = new(humanA)
    *peter = humanA{"Male", 30, 50.00}
    peter.printdetail()
}


Creating anonymous structs:
// Initializing a struct in a variable and declaring its values at the same time. Used for one time declaration.
    peter := struct{
        name string
        age int
    }{
        name: "BOB",
        age: 32,
    }

20. Data Analytics - Analyze Data to Answer Questions - Week 1

Goal of analysis is to identify trends and relationships within data so you can accurately answer the questions you're asking. Most data is organized in tables, always have data in the right format. Definition : Analysis // process used to make sense of the data collected Sorting // involves arranging data into a meaningful order to make it easier to understand, analyze, visualize Outliers // data points that are very different from similarly collected data and might not be reliable values Filtering // extracting specific data that meet certain criteria while hiding the rest Customized sort order // when you sort data in a spreadsheet using multiple conditions The 4 phases of analysis:          1. Organize data // getting the right data in the right size and order                     - Sorting : arrange data in meaningful order                     - Filtering : can help find errors or outliers          2. Format and adjust data // filtering or sorting or compiling data in a better

3. Algorithms - Selection Sort

Selection sort sorts an array by finding the lowest value element and appending it to an empty array. The algorithm will shrink the unsorted array and repeat the process recursively until all unsorted elements are used up. package main func selectionSort (list *[] int ) {     sorted := make ([] int , 0 , len (*list))     unSorted := *list     for i := 0 ; i < len (*list); i++ {         min := unSorted[ 0 ]         index := 0         for i , e := range unSorted {             if e <= min {                 min = e                 index = i             }         }         sorted = append (sorted, (unSorted)[index])         if index == 0 {             unSorted = unSorted[ 1 :]         } else if index == ( len (*list) - 1 ) {             unSorted = unSorted[:index]         } else {             unSorted = append (unSorted[ 0 :index], unSorted[index+ 1 :]...)         }     }     * list = sorted } /*func main() {     x := []int{4, 6, 3, 2, 9, 7, 3, 5}     fmt.Print
