CF1527A.And Then There Were K
And Then There Were K
Given an integer , find the maximum value of integer such that the following condition holds:
& () & () & () & ... () = where & denotes the bitwise AND operation.
Input
The first line contains a single integer (). Then test cases follow.
The first line of each test case contains a single integer ().
Output
For each test case, output a single integer — the required integer .
Note
In the first testcase, the maximum value for which the continuous & operation gives 0 value, is 1.
In the second testcase, the maximum value for which the continuous & operation gives 0 value, is 3. No value greater then 3, say for example 4, will give the & sum 0.
- ,
- .
Hence, 3 is the answer.
