用递归求一个数组中的最大数和最小值，算法思想是从数组的最后一个值向前比较-Recursive number of maximum and minimum values ​ ​ in an array, the algorithm thinking forward from the last value of the array

对输入的整型数组，输出数组元素中的最大值、最大值的个数、最小值和最小值的个数.根据数组知识结合指针进行实现。-Integer array of input and output array element maximum number of maximum, minimum, and the number of minimum. According to achieve a good array of knowledge.
