Python Copy The is_palindrome() method in the above code turns an integer into a string using the str(). The function returns True, indicating that the number is a palindrome if the length of the string is one o
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,...

python3 Determine whether an integer is a palindrome. Do this without extra space. Some hints: Could negative integers be palindromes? (ie, -1) If you are thinking of converting the integer to string, note the restriction of using extra space. You could also try reversing an integer. Howe...
Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input: 121 Output: true 1. 2. Example 2: Input: -121 Output: false Explanation: From left to right, it reads -121. From right to left, it becomes 121-....
