编写一个程序，读入一组整数，这组整数是按照从小到大的顺序排列的，它们的个数N也是由用户输入的，最多不会超过20。然后程序将对这个数组进行统计，把出现次数最多的那个数组元素值打印出来。如果有两个元素值出现的次数相同，即并列第一，那么只打印比较小的那个值。(Write a program, read into a group of integers, this group of integers are arranged in accordance with the order from small to large, the number of their N is also input by the user, at most not more than 20. The program then counts the array and prints out the array elements that appear most frequently. If two elements appear the same number of times, that is, first, then only the smaller one is printed.)
