Kotlin - Collections Fundamentals

Which of the following Kotlin code snippets correctly uses forEach to print all elements of val nums = listOf(1, 2, 3) each on a new line?

Anums.forEach { print(it) }

Bnums.forEach { println(it) }

Cnums.forEach println(it)

Dnums.forEach(println)

Step-by-Step Solution

Solution:

Step 1: Check syntax correctness
nums.forEach { println(it) } uses the correct lambda syntax with curly braces and println(it) to print each element on a new line.
Step 2: Analyze other options
nums.forEach println(it) misses braces, causing syntax error. nums.forEach { print(it) } prints without newline. nums.forEach(println) passes a function reference incorrectly.
Final Answer:
nums.forEach { println(it) } -> Option B
Quick Check:
Correct forEach print syntax = nums.forEach { println(it) } [OK]

Quick Trick: Use braces and println(it) inside forEach for line-by-line print [OK]
