LeetCode-9. Palindrome Number(回文数) 1.题目描述 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, ......
Have you consider that the string might be empty? This is a good question to ask during an interview. For the purpose of this problem, we define empty string as valid palindrome. 这道题没什么难的,就是考细心和对java的熟悉了,从两头往中间数,碰到非数字或letter的要跳过。 注意几点 1.当跳过...
