Selgitage välja IntRange tüübi eesmärgi ja kasutamise Kotlin keeles

In Kotlin, the IntRange type represents a range of integers and is used for working with sequences of numbers within a specified interval. It implements the ClosedRange<Int> interface, which allows for easy checking if a value belongs to the range, iterating over it, and using it in loops.

Example of using IntRange:

val range: IntRange = 1..5  // range from 1 to 5 inclusive

// Checking membership
println(3 in range)  // true
println(6 in range)  // false

// Iterating over the range
for (i in range) {
    println(i)
}

IntRange is often used in loops, conditions, and constraints where working with a set of consecutive integers is needed. It is convenient and safe because it is built into the language and supports all standard operations with ranges.
