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...
Hii. Here is your code. #include <iostream> using namespace std; int main() { int a,b,s=0; cout << "Hii. Enter a number: "; cin >> a; b=a; while(a!=0){ s=s*10+a%10; a/=10; } if(s==b) cout << "Palindrome."; else cout << "Not Palindrome." return 0; } ...
