Description

假设你工作在一个32位的机器上,你需要将某一个外设寄存器的第X位设置成0(最低位为第0位,最高位为第31位),将第Y位开始的连续三位设置成110(从高位到低位的顺序),而其他位保持不变。对给定的寄存器值R,及X,Y,编程计算更改后的寄存器值R。

Input

仅一行,包括R,X,Y,以逗号","分隔,R为16进制表示的32位整数,X,Y在0-31之间且Y>=3,(Y-X)的绝对值>=3,保证两次置位不会重合

Output

更改后的寄存器值R(16进制输出)

Sample Input

12345678,0,3

Sample Output

1234567c
