Kotlin - Loops and Ranges

Consider nested loops in Kotlin:

for (i in 1..3) {
    for (j in 1..3) {
        if (j == 2) break
        print("$i$j ")
    }
}

What is the output?

A11 21 31

B11 12 13 21 22 23 31 32 33

C11 12 21 22 31 32

D11 21 31 12 22 32

Step-by-Step Solution

Solution:

Step 1: Understand inner loop break condition
Inner loop breaks when j == 2, so it only prints when j == 1.
Step 2: Trace output for each outer loop iteration
For i=1, prints "11 "; i=2 prints "21 "; i=3 prints "31 ".
Final Answer:
11 21 31 -> Option A
Quick Check:
Break stops inner loop at j=2, prints only j=1 [OK]

Quick Trick: Break affects only inner loop here [OK]
