Break, next, and redo behavior in Ruby - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to exit the loop when the number is 5.

Ruby

numbers = [1, 2, 3, 4, 5, 6]
numbers.each do |num|
  if num == 5
    [1]
  end
  puts num
end

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'next' instead of 'break' which skips to the next iteration.

Using 'redo' which repeats the current iteration endlessly.

The break keyword exits the loop immediately when the condition is met.

2fill in blank

medium

Complete the code to skip printing the number 3 but continue the loop.

Ruby

numbers = [1, 2, 3, 4, 5]
numbers.each do |num|
  if num == 3
    [1]
  end
  puts num
end

💡 Hint

Common Mistakes

Using 'break' which stops the entire loop.

Using 'redo' which repeats the current iteration endlessly.

The next keyword skips the current iteration and continues with the next one.

3fill in blank

hard

Fix the error in the code to repeat the current iteration when the number is even.

Ruby

numbers = [1, 2, 3]
numbers.each do |num|
  if num.even?
    [1]
  end
  puts num
end

💡 Hint

Common Mistakes

Using 'next' which skips to the next iteration.

Using 'retry' which is not valid inside this loop context.

The redo keyword repeats the current iteration without moving to the next element.

4fill in blank

hard

Fill both blanks to skip printing 2 and stop the loop at 4.

Ruby

numbers = [1, 2, 3, 4, 5]
numbers.each do |num|
  if num == 2
    [1]
  elsif num == 4
    [2]
  end
  puts num
end

💡 Hint

Common Mistakes

Using 'break' to skip 2 which stops the whole loop.

Using 'redo' which repeats the iteration endlessly.

Use next to skip printing 2 and break to stop the loop at 4.

5fill in blank

hard

Fill all three blanks to repeat the iteration for odd numbers, skip 4, and stop at 5.

Ruby

numbers = [1, 2, 3, 4, 5]
numbers.each do |num|
  if num.odd?
    [1]
  elsif num == 4
    [2]
  elsif num == 5
    [3]
  end
  puts num
end

💡 Hint

Common Mistakes

Using 'next' instead of 'redo' for repeating.

Using 'break' too early stopping the loop before intended.

Use redo to repeat the iteration for odd numbers, next to skip 4, and break to stop at 5.
