NITK04 - DEEPIKA AND HER BANK ACCOUNT
Ranbir has deposited some money in Deepika's account. Deepika would like to withdraw X $US from an ATM. The ATM machine will only accept the transaction if X is a multiple of 10, and Deepika's account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US.
Calculate Deepika's account balance after an attempted transaction.
Input
The first like contains T (T < 20), the number of test cases followed by T lines each containing X and Y.
Positive integer 0 < X <= 2000 - the amount of cash which Deepika wishes to withdraw.
Nonnegative number 0 <= Y <= 2000 with two digits of precision - Deepika's initial account balance.
Output
Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance.
Example
Input: 2 30 120.00 42 120.00 Output: 89.50 120.00
