如何编写复杂的Kotlin for循环

for (i in 1..10) {
    println(i)
}

for (i in 1..10 step 2) {
    println(i)
}

for (i in 1..10) {
    if (i % 2 == 0) {
        println("$i 是偶数")
    } else {
        println("$i 是奇数")
    }
}

for (i in 1..3) {
    for (j in 1..3) {
        println("i = $i, j = $j")
    }
}

val numbers = listOf(1, 2, 3, 4, 5)
numbers.forEach { number ->
    println(number * 2)
}

val fruits = listOf("apple", "banana", "cherry")
for ((index, fruit) in fruits.withIndex()) {
    println("Fruit at index $index is $fruit")
}

for (i in 0 until 10) {
    println(i)
}

for (i in 1..100) {
    if (i % 3 == 0 && i % 5 == 0) {
        println("$i 是3和5的公倍数")
    } else if (i % 3 == 0) {
        println("$i 是3的倍数")
    } else if (i % 5 == 0) {
        println("$i 是5的倍数")
    }
}
