Minimum Withdrawal Count

Little A wants to purchase an item that costs \(a\) yuan, but he only has \(b\) yuan in cash. He may need to withdraw more money from a bank. The ATM dispenses an unlimited number of \(100\)-yuan bills. Given the values of \(a\) and \(b\), determine the minimum number of \(100\)-yuan bills Little A must withdraw so that he can afford the item.

If \(b \ge a\), then no withdrawal is needed.

inputFormat

The input consists of a single line containing two integers \(a\) and \(b\) \((1 \le a, b \le 10^9)\), where \(a\) is the price of the item and \(b\) is the amount of cash Little A currently has.

outputFormat

Output a single integer representing the minimum number of \(100\)-yuan bills Little A needs to withdraw in order to have at least \(a\) yuan.
