1. Start from the leftmost side of the path.
2. Push the first boulder (the one farthest to the left) to the right.
3. Push the second boulder (now in the leftmost position) to the right.
4. Push the third boulder (now the leftmost one) to the right.
5. Push the fourth boulder (the leftmost one) to the right.
Now the path should be clear, allowing you to proceed further.
Important Note: If you're having trouble visualizing this, imagine pushing the boulders one by one like a chain reaction. You're basically shuffling them all the way to the right.
