The following procedure finds the highest amount of bill generated at Sun General from the Shopping Bills dataset. But the programmer may have made mistakes in one or more steps. Identify all such steps (if any).
Step 1. Arrange all cards in a single pile called Pile 1
Step 2. Maintain a variable max and initialize it to 0
Step 3. If Pile 1 is empty then stop the iteration
Step 4. Read the top card in Pile 1
Step 5. If the shop name is Sun General and max > total bill amount then store total bill amount in max
Step 6. Move the current card to another pile called Pile 2 and repeat from step 3
