1024 Palindromic Number (25 分)   A number that will be the same when it is written forwards or backwards is known as a Palindromic Number. For example, 1234321 is a palindromic number. All single digit numbers are palindromic numbers. Non-palindromic…

A number that will be the same when it is written forwards or backwards is known as a Palindromic Number. For example, 1234321 is a palindromic number. All single digit numbers are palindromic numbers. Non-palindromic numbers can be paired with palin…

题意: 输入两个正整数N和K(N<=1e10,k<=100),求K次内N和N的反置相加能否得到一个回文数,输出这个数和最小的操作次数. trick: 1e10的数字相加100次可能达到1e40,所以long long会爆,采用字符数组操作,以及代码注释中遇到的一些小问题. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ]; ];//这里用str…

25 [程序 25 求回文数] 题目:一个 5 位数,判断它是不是回文数.即 12321 是回文数,个位与万位相同,十位与千位相同. package cskaoyan; public class cskaoyan25 { @org.junit.Test public void palindromic() { java.util.Scanner in = new java.util.Scanner(System.in); long number = in.nextLong(); String st…

Given a string s, find the longest palindromic subsequence's length in s. You may assume that the maximum length of s is 1000. Example 1:Input: "bbbab" Output: 4 One possible longest palindromic subsequence is "bbbb". Example 2:Input:…
