Swift - Loops

What will be the output of this Swift code?

var sum = 0
for i in 1...5 {
    if i == 4 {
        break
    }
    sum += i
}
print(sum)

A6

B15

C10

D0

Step-by-Step Solution

Solution:

Step 1: Trace the loop and break condition
The loop adds numbers from 1 to 5, but breaks when i is 4, so it stops before adding 4.
Step 2: Calculate sum before break
Sum = 1 + 2 + 3 = 6; loop breaks before adding 4, so sum is 6.
Step 3: Recheck sum calculation
Wait, sum is 6, but 10 says 10. Let's re-examine: 1+2+3=6, so 6 is correct.
Final Answer:
6 -> Option A
Quick Check:
Break stops loop before adding 4, sum = 6 [OK]

Quick Trick: Break stops loop early, sum excludes 4 and 5 [OK]
