Ruby - Loops and Iteration

count = 0
while count < 3
  count += 1
  if count == 2
    redo
  end
  puts count
end

A1 2 2 3

B1 2 2 2 ...

C1 3

D1 2 3

Step-by-Step Solution

Solution:

Step 1: Analyze loop and redo
When count == 2, redo repeats the current iteration without incrementing count.
Step 2: Effect of redo here
Since count is not incremented again inside the loop, it stays 2, causing infinite repeats printing 2.
Final Answer:
1 2 2 2 ... (infinite loop) -> Option B
Quick Check:
redo repeats iteration without changing variables [OK]

Quick Trick: Redo repeats iteration without increment, causing infinite loop [OK]
