Problem

You are given an array  of size . In one operation, you can do the following:

  • Select indices  and  (�≠�) and set ��=��.

Find the minimum number of operations required to make all elements of the array equal.

Input Format

  • The first line of input will contain a single integer , denoting the number of test cases.
  • Each test case consists of multiple lines of input.
    • The first line of each test case contains an integer  — the size of the array.
    • The next line contains  space-separated integers, denoting the array .

Output Format

For each test case, output on a new line, the minimum number of operations required to make all elements of the array equal.

Constraints

  • 1≤�≤1000
  • 1≤�≤2⋅105
  • 1≤��≤�
  • The sum of  over all test cases won’t exceed 2⋅105.

Sample 1:

Output

3
3
1 2 3
4
2 2 3 1
4
3 1 2 4
2
2
3

Explanation:

Test case 1: The minimum number of operations required to make all elements of the array equal is 2. A possible sequence of operations is:

  • Select indices 1 and 2 and set �1=�2=2.
  • Select indices 3 and 2 and set �3=�2=2.

Thus, the final array is [2,2,2].

Test case 2: The minimum number of operations required to make all elements of the array equal is 2. A possible sequence of operations is:

  • Select indices 3 and 2 and set �3=�2=2.
  • Select indices 4 and 3 and set �4=�3=2.

Thus, the final array is [2,2,2,2].

Test case 3: The minimum number of operations required to make all elements of the array equal is 3. A possible sequence of operations is:

  • Select indices 2 and 1 and set �2=�1=3.
  • Select indices 3 and 1 and set �3=�1=3.
  • Select indices 4 and 1 and set �4=�1=3.

Thus, the final array is [3,3,3,3].
