You are given an array (a_1, a_2, \ldots, a_n). You may perform the following operation: For all indices (i) ((1 \leq i \leq n)), set (a_i = |a_i - 2|). Find the maximum possible frequency of any integer in (a) after performing the operation an arbitrary number (possibly zero) of times. The first line of each input contains an integer (t) ((1 \leq t \leq 10^4)) — the number of test cases. The first line of each test case contains an integer (n) ((1 \leq n \leq 2 \cdot 10^5)) — the length of (a). The second line of each test case contains (n) integers (a_1, a_2, \ldots, a_n) ((1 \leq a_i \leq 10^9)) — the array (a). It is guaranteed that the sum of (n) over all test cases does not exceed (2 \cdot 10^5). For each test case, output a single integer denoting the maximum possible frequency of any integer in (a) after performing the operation an arbitrary number of times. In the first test case, we can perform the operation once to have (a = |1 - 2|, |3 - 2| = 1, 1), which means the maximum possible frequency of any integer in (a) is (2). In the second test case, the maximum frequency of an integer in (a) is (3). It can be shown that, no matter how many operations we perform, the maximum possible frequency of an integer in (a) will never exceed (3).
