题目描述

You are given an array consisting of all integers from $[l, r]$ inclusive. For example, if $l = 2$ and $r = 5$ , the array would be $[2, 3, 4, 5]$ . What's the minimum number of elements you can delete to make the [bitwise AND](https://en.wikipedia.org/wiki/Bitwise_operation#AND) of the array non-zero?

A bitwise AND is a binary operation that takes two equal-length binary representations and performs the AND operation on each pair of the corresponding bits.

输入格式

The first line contains one integer $t$ ( $1 \leq t \leq 10^4$ ) — the number of test cases. Then $t$ cases follow.

The first line of each test case contains two integers $l$ and $r$ ( $1 \leq l \leq r \leq 2 \cdot 10^5$ ) — the description of the array.

输出格式

For each test case, output a single integer — the answer to the problem.
