+LeetCode Problem 384: Shuffle an Array
+
+Description:
+Given an integer array nums, design an algorithm to randomly shuffle the array.
+All permutations of the array should be equally likely as a result of the shuffling.
+
+Implementation of the Solution class:
+- Solution(int[] nums): Initializes the object with the integer array nums.
+- int[] reset(): Resets the array to its original configuration and returns it.
+- int[] shuffle(): Returns a random shuffling of the array.
+
+Example Usage:
+const solution = new Solution([1, 2, 3]);
+console.log(solution.shuffle()); // Example output: [3, 1, 2]
+console.log(solution.reset());   // Output: [1, 2, 3]
+console.log(solution.shuffle()); // Example output: [1, 3, 2]
+
+Constraints:
+- 1 <= nums.length <= 50
+- -10^6 <= nums[i] <= 10^6
+- All elements in nums are unique.
+- At most 10,000 calls in total will be made to reset and shuffle.
