Submitted by IncludeHelp, on May 12, 2020

Given an integer number, we have to check whether it is perfect square or not.

Example:

    Input:
    num = 25

    Output:
    Perfect Square

    Input:
    num = 67

    Output:
    Not a Perfect Square

Program to check if given number is perfect square in Kotlin

package com.includehelp

import java.util.*
//import kotlin.math.floor
//import kotlin.math.sqrt

//function to check perfect Square number
fun checkPerfectSquare(number:Double):Boolean{
	//Square Root of Number
	val sq= Math.sqrt(number)

	//Floor value, nearest Integer Part  floor(983.2) = 983
	val f = Math.floor(sq)

	return sq==f
}

//Main Function , Entry point of Program
fun main(args: Array<String>) {

	//Input Stream
	val scanner = Scanner(System.`in`)

	//Input Length of Rectangle
	print("Enter Number : ")
	val number = scanner.nextDouble()

	//check Number and Print Result
	if(checkPerfectSquare(number)) 
		println("$number is Perfect Square") 
	else 
		println("$number is Not Perfect Square")
}

Output

Run 1:
Enter Number : 25
25.0 is Perfect Square
---
Run 2:
Enter Number : 67
67.0 is Not Perfect Square
