Kotlin - Loops and Ranges

What will be the output of this Kotlin code?

outerLoop@ for (a in 1..2) {
  innerLoop@ for (b in 1..3) {
    if (b == 2) continue@outerLoop
    print("$a$b ")
  }
}

A11 13 21 23

B11 12 13 21 22 23

C11 21

D12 13 22 23

Step-by-Step Solution

Solution:

Step 1: Understand loops
Outer loop a=1..2, inner loop b=1..3.
Step 2: Condition and continue@outerLoop
When b==2, continue@outerLoop skips to next iteration of outer loop.
Step 3: Output reasoning
For a=1: b=1 prints "11 ", b=2 triggers continue@outerLoop (skip rest of inner loop and increment a). For a=2: b=1 prints "21 ", b=2 triggers continue@outerLoop again.
Final Answer:
11 13 21 23 -> Option A
Quick Check:
continue@outerLoop skips inner loop rest and continues outer [OK]

Quick Trick: continue@label skips to next iteration of labeled loop [OK]
