Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input:121Output:true Example 2: Input:-121Output:falseExplanation:From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not ...
Coud you solve it without converting the integer to a string? 代码: staticvoidMain(string[] args) {intnum =123321;boolresult =Palindromenumber(num); Console.WriteLine(result); Console.ReadKey(); }privatestaticboolPalindromenumber(intnum) {if(num <0)returnfalse;vararr =num.ToString().ToCharArr...
Explanation: Reads 01 from right to left. Therefore it is not a palindrome. Follow up: Coud you solve it without converting the integer to a string? 注:直接用栈和队列做的,时间复杂度有点大。Runtime: 120 ms, faster than 48.36% of C online submissions for Palindrome Number. 等有时间再想想...
1.基于数学取模,参考整数反转leetcode007,得到反转后的数字后,保证边界情况下进一步看值是否相等,时间O(n),空间O(1) 2.基于字符串字符双指针比较,时间O(n),空间O(1) 时间效率一样,空间效率数学取模法更优。 python # 基于数学取模比较值,参考整数反转 def is_palindrome_number(num: int) -> bool: ""...
"a word, verse, or sentence (as “Able was I ere I saw Elba” or a number (as 1881) that reads the same backward or forward" your initial response (the one that could have easily been spoiler tagged btw) still remains garbage and inapplicable, soz, and merely designed to ...
