Problem

Chef has an array A of length N.

In one operation, Chef can choose any subsequence of the array and any integer X and then add X to all the elements of the chosen subsequence.

Determine the minimum number of operations required to make all the elements of the array distinct.

Input Format

  • The first line of input will contain a single integer T, denoting the number of test cases.
  • Each test case consists of multiple lines of input.
    • The first line of each test case contains a single integer N — the length of Array A.
    • Next line contains N space-separated integers A_1, A_2, A_3, \dots, A_N – denoting the array A.

Output Format

For each test case, output the minimum number of operations required to make all the elements distinct.

Constraints

  • 1 \leq T \leq 4000
  • 1 \leq N \leq 10^5
  • 1 \leq A_i \leq 10^9
  • Sum of N over all test cases do not exceed 3 \cdot 10^5

Explanation:

Test case 1:

  • Operation 1: Choose the subsequence \{A_1\} and add X = 1 to the elements. The array becomes A = [4, 3, 3].
  • Operation 2: Choose the subsequence \{A_2\} and add X = 2 to the elements. The array becomes A = [4, 5, 3].

Thus, we require, minimum 2 operations to make all the elements distinct.

Test case 2:

  • Operation 1: Choose the subsequence \{A_1, A_6\} and add X = 4 to the elements. The array becomes A = [5, 3, 2, 1, 2, 6].
  • Operation 2: Choose the subsequence \{A_3\} and add X = 5 to the elements. The array becomes A = [5, 3, 7, 1, 2, 6].

Thus, we require, minimum 2 operations to make all the elements distinct.

Test case 3:

  • Operation 1: Choose the subsequence \{A_3, A_4\} and add X = 2 to the elements. The array becomes A = [1, 2, 3, 4].

Thus, we require, minimum 1 operation to make all the elements distinct.

Test case 4: All the elements are distinct. We need zero operations.
