从给定的一组数组中，寻找当前数组中的多数元素，其中多数元素的定义为其在数组中的个数大于其数组元素个数的一半，该算法采用递归的方式，求得其多数元素的候选值，然后进行验证，最终求得结果-A group from a given array to find the majority of the current array element for most of the elements in the array defines the number of greater than half the number of array elements, the algorithm uses a recursive manner, and seek their Most elements of the candidate value, and then verify the final results obtained
