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
```
