Kotlin program to find smallest element in an array

Kotlin | Smallest element in an array: Here, we are going to learn how to find the smallest element in a given array in Kotlin programming language?
Submitted by IncludeHelp, on May 05, 2020

Given an array, we have to find the smallest element.

Example:

    Input:
    arr = [3, 9, 0, -45, -3, 87]

    Output:
    Smallest element: -45

Program to find smallest element in an array in Kotlin

package com.includehelp

import java.util.*

//Main Function entry Point of Program
fun main(args: Array<String>) {
    //Input Stream
    val s = Scanner(System.`in`)

    //Input Array Size
    print("Enter number of elements in the array: ")
    val size = s.nextInt()

    //Create Integer array of Given size
    val intArray = IntArray(size)

    //Input array elements
    println("Enter Arrays Elements:")
    for (i in intArray.indices) {
        print("intArray[$i] : ")
        intArray[i] = s.nextInt()
    }

    //Alternatively we can also use min() method of Arrays Class 
    //in kotlin to find minimum Array Element
    var minimum = intArray.min()

    //Print Array elements
    println("Array : ${intArray.contentToString()} ")

    //Print minimum value of Array
    println("Minimum Element of Array is : $minimum")
}

Output

Run 1:
-----
Enter number of elements in the array: 6
Enter Arrays Elements:
intArray[0] : 3
intArray[1] : 9
intArray[2] : 0
intArray[3] : -45
intArray[4] : -3
intArray[5] : 87
Array : [3, 9, 0, -45, -3, 87]
Minimum Element of Array is : -45
--------
Run 2:
----
Enter number of elements in the array: 7
Enter Arrays Elements:
intArray[0] : 3
intArray[1] : 9
intArray[2] : 34
intArray[3] : 2
intArray[4] : 87
intArray[5] : 123
intArray[6] : 56
Array : [3, 9, 34, 2, 87, 123, 56]
Minimum Element of Array is : 2
