用java实现分治法求众数算法

好的，以下是用Java实现分治法求众数算法的代码：

public class MajorityElement {
    public int majorityElement(int[] nums) {
        return majorityElement(nums, 0, nums.length - 1);
    }
    
    private int majorityElement(int[] nums, int start, int end) {
        if (start == end) {
            return nums[start];
        }
        int mid = (end - start) / 2 + start;
        int leftMajority = majorityElement(nums, start, mid);
        int rightMajority = majorityElement(nums, mid + 1, end);
        if (leftMajority == rightMajority) {
            return leftMajority;
        }
        int leftCount = count(nums, leftMajority, start, end);
        int rightCount = count(nums, rightMajority, start, end);
        return leftCount > rightCount ? leftMajority : rightMajority;
    }
    
    private int count(int[] nums, int num, int start, int end) {
        int count = 0;
        for (int i = start; i <= end; i++) {
            if (nums[i] == num) {
                count++;
            }
        }
        return count;
    }
}

以上是分治法求众数算法的Java实现，希望可以帮助您解决问题。如果还有其他问题，请随时提出。
