The following Python code uses recursion to determine whether an integer is a palindrome: def is_palindrome(num): str_num = str(num) if len(str_num) <= 1: return True else: if str_num[0] != str_num[-1]: return False else: return is_palindrome(str_num[1:-1]) print(is_...
题目:Determine whether an integer is a palindrome. Do this without extra space. 刚开始看到题目的时候想着用栈来处理,每进来一个数与栈顶元素比较相同则栈顶元素处栈,不同则元素入栈,最后栈为空或剩一个数为真,我是以“1234321”来考虑的,但是提交的时候发现存在“100”此种情况,因此分为两种类型来处理,...
