Ruby - Loops and Iteration

You want to print numbers 1 to 5 but skip 3 and repeat printing 4 twice using next and redo. Which code achieves this correctly?

i = 0
while i < 5
  i += 1
  if i == 3
    # skip 3
  elsif i == 4
    # print 4 twice
  end
  puts i
end

Aif i == 3 next elsif i == 4 puts i redo next end

Bif i == 3 next elsif i == 4 redo end

Cif i == 3 next elsif i == 4 puts i redo end

Dif i == 3 redo elsif i == 4 next end

Step-by-Step Solution

Solution:

Step 1: Skip number 3 using next
Using next when i == 3 skips printing 3 and moves to next iteration.
Step 2: Repeat printing 4 twice using redo
When i == 4, print it once, then use redo to repeat the iteration and print 4 again.
Step 3: Verify code correctness
if i == 3 next elsif i == 4 puts i redo end prints 4, then calls redo to repeat printing 4, and skips 3 correctly. Other options misuse next or redo causing errors or infinite loops.
Final Answer:
if i == 3 next elsif i == 4 puts i redo end -> Option C
Quick Check:
next skips, redo repeats current step [OK]

Quick Trick: Use next to skip, redo after puts to repeat [OK]
