In particular, no function should ever need to accessany element of the list more than once. (i.e, don’t go through the entire list once to find the max, and againto find the min).不能用到内置函数 只能用递归来做搞了一晚上了想不
给定一个整数数组,请编写一个函数,找出数组中第二大的数。如果数组长度小于2,则返回-1。```pythondef find_second_max(nums):if len(nums) first_max:second_max = first_maxfirst_max = numelif num > second_max and num != first_max:second_max = numreturn second_max
