Array

// ARRAY
// 1.
var arr1 : [Int] = [10,20,30]

var val1 = arr1[0]
print("First value : ", val1)
print("Second value : ", arr1[1])
print("Thirdvalue : ", arr1[2])

// 2. Iterator

for item in arr1{
print(item)
}

// 3. append
print("*********APPEND************")
var arr2 = [Int]() ;
arr2.append(5)
arr2.append(55)
arr2.append(555)
for item in arr2{
print(item)
}

// 4. assigning new value to old
print("***********assigning value on above record**************")
arr2[1] = 999
for item in arr2{
print(item)
}

// 5. adding two array
print("**********ADDING TWO ARRAY************")
var arr3 : [Int] = arr1 + arr2
for item in arr3{
print(item)
}

//6. count
print("*************COUNT PROPERTY*******************")
print("Array size (arr3.count) : \(arr3.count)")

//7. isEmpty
print("*************isEmpty Property***************")
var arr4 = [Int]()
print("arr3 isEmpty : \(arr3.isEmpty)")
print("arr4 isEmpty : \(arr4.isEmpty)")


****************************************************
8. Pass one function array to secind using global array.

CODE </ >

var marksGlobalArray : Array<Int> = []

func first(){
    let marksArray: [Int] = [10, 20, 30, 40, 50]
    for mark in marksArray{
        marksGlobalArray.append(mark)
    }   
}

func second(){
    print(first())
    for a1 in marksGlobalArray{
        print(a1)
    }
}
// CALL
second()

***********************************************************

9.  Sort

var array : [String] = ["Test", "John", "Mike", "Divakar", "Anuj", "Somya"]

or var array : [Int] = [23, 98, 56, 72, 49]

array.sort(by: <) // will sort the array in ascending order
array.sort(by: >) // will sort the array in descending order

// you can also use the sorted method to create a sorted copy
let sortedArray = array.sorted(by: <)

10. Filter

A.

let arr = ["Ram", "Mohan", "Shyam", "John"]

let filtered = arr.filter { $0.contains("am") }

print(filtered)

Output : ["Ram", "Shyam"]

//

B. 

let terms = ["Hello","Bye","Halo"]

var filterdTerms = [String]()

func filterContentForSearchText(searchText: String) {

    filterdTerms = terms.filter { term in

        return term.lowercased().contains(searchText.lowercased())

    }

}

filterContentForSearchText(searchText: "Lo")

print(filterdTerms)

Output : ["Hello", "Halo"]
