Kotlin - Loops and Ranges

for (i in 1..7 step 3) {
    print(i)
}

A1 3 6

B1 4 7

C1 4 6

D1 3 5 7

Step-by-Step Solution

Solution:

Step 1: Identify loop values with step 3
Start at 1, add 3 each time until 7: 1, 4, 7.
Step 2: Confirm loop stops at or before 7
Next step after 7 would be 10 which is beyond 7, so loop ends.
Final Answer:
1 4 7 -> Option B
Quick Check:
Range with step 3 outputs 1 4 7 [OK]

Quick Trick: Add step value each iteration until reaching end [OK]
