koltin measureTimeMillis

        // Code block to measure execution time
        for (i in 1..1_000_000) {
            // Simulating some task to measure execution time

• measureTimeMillis is a higher-order function in Kotlin used to measure the time taken for the execution of a specific code block.
• fun main() { ... } is the entry point of the Kotlin program.
• val executionTime = measureTimeMillis { ... } creates a variable executionTime to store the elapsed time during the execution of the code block provided within the curly braces.
• for (i in 1..1_000_000) { ... } is a loop iterating from 1 to 1,000,000, simulating a task to measure execution time.
• val result = i * i performs a simple calculation to simulate a computational task within the loop.
• println("Execution time: $executionTime ms") prints the elapsed time in milliseconds once the code block inside measureTimeMillis completes execution.
