题目描述
A state with $n$ flags of ON or OFF can be represented by a sequence of bits where $0, 1, ..., n-1$ -th flag corresponds to 1 (ON) or 0 (OFF). The state can be managed by the corresponding decimal integer, because the sequence of bits is a binary representation where each bit is 0 or 1.
Given a sequence of bits with 64 flags which represent a state, perform the following operations. Note that each flag of the bits is initialized by OFF.
- test(i): Print 1 if $i$-th flag is ON, otherwise 0
- set(i): Set $i$-th flag to ON
- clear(i): Set $i$-th flag to OFF
- flip(i): Inverse $i$-th flag
- all: Print 1 if all flags are ON, otherwise 0
- any: Print 1 if at least one flag is ON, otherwise 0
- none: Print 1 if all flags are OFF, otherwise 0
- count: Print the number of ON flags
- val: Print the decimal value of the state
Constraints
- $1 \leq q \leq 200,000$
- $0 \leq i < 64$
Input
The input is given in the following format.
$q$
$query_1$
$query_2$
:
$query_q$
Each query $query_i$ is given in the following format:

The first digit 0, 1,...,8 represents the operation test(i), set(i), clear(i), flip(i), all, any, none, count or val respectively.
Output
Print the result in a line for each test, all, any, none, count and val operation.
