Labeled break and continue in Kotlin - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to break out of the outer loop using a label.

Kotlin

outer@ for (i in 1..3) {
    for (j in 1..3) {
        if (i == 2 && j == 2) {
            [1]@outer
        }
        println("i = $i, j = $j")
    }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using continue instead of break causes the loop to skip to next iteration.

Using return exits the function, not just the loop.

Using break@outer exits the outer loop immediately.

2fill in blank

medium

Complete the code to continue the outer loop when a condition is met.

Kotlin

outer@ for (i in 1..3) {
    for (j in 1..3) {
        if (i == 1 && j == 2) {
            [1]@outer
        }
        println("i = $i, j = $j")
    }
}

💡 Hint

Common Mistakes

Using break exits the loop instead of continuing.

Using return exits the function, not just the loop.

Using continue@outer skips the current iteration of the outer loop.

3fill in blank

hard

Fix the error in the code to correctly use a labeled continue.

Kotlin

loop@ for (x in 1..3) {
    for (y in 1..3) {
        if (x == 2 && y == 1) {
            [1]@loop
        }
        println("x = $x, y = $y")
    }
}

💡 Hint

Common Mistakes

Using break instead of continue causes the loop to exit.

Using undefined keywords like skip or exit causes errors.

The correct keyword to skip to the next iteration of the labeled loop is continue.

4fill in blank

hard

Fill both blanks to create a labeled break and continue in nested loops.

Kotlin

outer@ for (a in 1..3) {
    inner@ for (b in 1..3) {
        if (a == 2 && b == 2) {
            [1]@outer
        }
        if (a == 1 && b == 3) {
            [2]@inner
        }
        println("a = $a, b = $b")
    }
}

💡 Hint

Common Mistakes

Mixing up break and continue keywords.

Using return or exit which are not valid for loops.

break@outer exits the outer loop, and continue@inner skips to the next iteration of the inner loop.

5fill in blank

hard

Fill all three blanks to use labeled break and continue correctly in nested loops with conditions.

Kotlin

loop1@ for (i in 1..3) {
    loop2@ for (j in 1..3) {
        if (i == 3 && j == 1) {
            [1]@loop1
        }
        if (i == 2 && j == 3) {
            [2]@loop2
        }
        println("i = $i, j = $j")
        if (i == 1 && j == 2) {
            [3]@loop2
        }
    }
}

💡 Hint

Common Mistakes

Using return or exit which are not valid loop controls.

Confusing which label to use with break or continue.

break@loop1 exits the outer loop, and continue@loop2 skips iterations of the inner loop.
