Your code fails here-

Input
50 50.00

Your Output
-0.50

Expected Output
50.00 (as "If there is not enough money in the account to complete the transaction (+the bank fees), output the current bank balance.")

Problem with your code-

  1. Try to find details in the problem like when to use < and when to use <=.

  2. You didn’t take into account the extra charges the bank requires of 0.05 for every transaction done. So your current balance should be withdrawl amount + $0.05.

Solution -

Just change the following line of your code - if(x%5==0&&x<=y) to - if(x%5==0&&x+0.05<y)

No, its not correct. The total cost in my test case is 50.50, while balance had only $50. Re-check the expected output

You may need to change this condition-

“if(x%5==0&&x<=y)”

Make it check if her balance> withdrawing amount+0.5
