Minimize Hamming Distance Problem

Ninja has strategically formed a team to combat enemies in his city. Each ninja in the team has a specific range of attack, and the team has successfully acquired the attack range information of their enemies. To optimize the attack strategy, ninja allows swaps between team members to minimize the Hamming distance, which is the count of differing positions between elements of the two arrays.

Input:

Given two arrays 'ninja' and 'enemies', both of the same length, and an 'allowedSwaps' array where each element [ai, bi] indicates the indices in the 'ninja' array which can be swapped.

Output:

Return the minimum Hamming distance between 'ninja' and 'enemies' after performing any number of such allowed swaps.

Example:

Input:
ninja = [1, 2, 3, 4] enemies = [2, 1, 4, 5] allowedSwaps = [[0, 1], [2, 3]]
Output:
1
Explanation:

By swapping indices 0 and 1, and 2 and 3, the ninja array becomes [2, 1, 4, 3], minimizing the Hamming distance to 1.

Constraints:

  • 1 ≤ T ≤ 100
  • 1 ≤ N ≤ 10^3
  • 1 ≤ ninja[i], enemies[i] < 10^5
  • 0 ≤ allowedSwaps.length ≤ 10^5

Note: Implement the function as specified. Do not handle output or input formatting.
