How many times does the loop run?
Short answer. 4 times, because k becomes -2 on the fifth check.
What is the final value of sum?
22.
Remember
| Move parts, keep values |
| Trace to count rounds |
Board question. Convert it, and count the rounds. Move k equals ten above. K goes ten, seven, four, one. So it runs four times, and sum is twenty two. Move the parts, but keep the values. Trace to count the rounds.
