Sample Solution: C Code: #include<stdio.h>#include<string.h>#include<ctype.h>// Define a function pointer type that takes two characters and returns an integer.typedefint(*compare_func_t)(char,char);// This function checks if a given string is a palindrome.// It takes a string, its ...
The result, , is now a palindrome.解题思路:贪心。仅仅考虑一边的情况就可以,以左半为例。不断贪心考虑pos离哪边的不匹配边界近,如此往复就可以。AC代码:#include <iostream> #include <cstdio> #include <string> #include <cmath> using namespace std; int main(){ int n, pos; string s; // fr...

I think I just figured out how it's done and made a code for it, honestly this way of Palindrome checking is kinda new to me, as I'm more familiar with the common method, by comparing the characters from each of the opposite end of the string and don't usually bother removing white...

Coud you solve it without converting the integer to a string? 代码: boolisPalindrome(intx) {if(x<0)returnfalse;if(x==0)returntrue;inta[100],i,j,sum;for(i=0;x!=0;i++) { a[i]=x%10; x/=10; } sum=i; i--;if(a[0]==0)returnfalse;for(j=0;j<sum/2;j++,i--)if(a...

palindrome (回文)是一个对称的单词或句子,它的前后拼写相同,忽略了大小写和标点符号。下面是一个简短而低效的程序来反转回文字符串。它调用字符串方法charAt(i),该方法返回字符串中的第i个字符,从0开始计数。 public class StringDemo { public static void main(String[] args) { String palindrome = "Dot sa...
