🌟 Problem Description:
In this problem, you run a lemonade stand where each lemonade costs $5. Customers may pay with $5, $10, or $20 bills. Your goal is to determine whether you can provide the correct change to each customer in line.
🔑 Code Explanation:
Variables: Two variables, fiveCount and tenCount, track the number of $5 and $10 bills you have.
Loop Through Bills: For each bill:
If the bill is $5, increase fiveCount.
If the bill is $10, check if you can give $5 as change. If yes, decrease fiveCount and increase tenCount; otherwise, return false.
If the bill is $20, check if you can give $15 as change, either with one $10 and one $5 bill or three $5 bills. If not possible, return false.
Final Return: If you can provide the correct change to all customers, return true.
