CF2026E Best Subsequence
Description
Given an integer array $ a $ of size $ n $ .
Let's define the value of the array as its size minus the number of set bits in the bitwise OR of all elements of the array.
For example, for the array $ [1, 0, 1, 2] $ , the bitwise OR is $ 3 $ (which contains $ 2 $ set bits), and the value of the array is $ 4-2=2 $ .
Your task is to calculate the maximum possible value of some subsequence of the given array.
Input Format
The first line contains a single integer $ t $ ( $ 1 \le t \le 100 $ ) — the number of test cases.
The first line of each test case contains a single integer $ n $ ( $ 1 \le n \le 100 $ ).
The second line of each test case contains $ n $ integers $ a_1, a_2, \dots, a_n $ ( $ 0 \le a_i < 2^{60} $ ).
Output Format
For each test case, print the maximum possible value of some subsequence of the given array.
