Kotlin – Smallest of Three Numbers

How to Find Smallest Number of Three Numbers in Kotlin

In Kotlin, finding the smallest of three numbers involves comparing the numbers and identifying the smallest value among them. We will use Kotlin minOf() function to find the smallest number.

Examples

Example 1: Find the Smallest of Three Numbers

Let’s start with an example of finding the smallest of three numbers.

We’ll create a function that takes three integers as input and returns the smallest value among them.

Kotlin Program

fun findSmallest(num1: Int, num2: Int, num3: Int): Int {
    return minOf(num1, num2, num3)
}

fun main() {
    // Test the function with sample numbers
    val num1 = 10
    val num2 = 5
    val num3 = 8
    val smallest = findSmallest(num1, num2, num3)
    println("The smallest of $num1, $num2, and $num3 is: $smallest")
}

Output

The smallest of 10, 5, and 8 is: 5

In the function,

• We define a function findSmallest that takes three integers as input: num1, num2, and num3.
• Inside this function, we use the minOf function to find the smallest value among the three numbers.
• The minOf function automatically compares the provided arguments and returns the smallest value.

Summary

In Kotlin, you can find the smallest of three numbers by using the minOf() function, which returns the smallest value among the provided arguments.
