palindrome program in c++
#include <iostream>
bool isPalindrome (int number) {
int decomposed = number, reversed = 0;
while (decomposed) {
reversed = 10 * reversed + (decomposed % 10);
decomposed /= 10;
}
return reversed == number;
}check if a string is palindrome cpp
// Check whether the string is a palindrome or not.
#include <bits/stdc++.h>
using namespace std;
int main(){
string s;
cin >> s;
int l = 0;
int h = s.length()-1;
while(h > l){
if(s[l++] != s[h--]){
cout << "Not a palindrome" << endl;
return 0;
}
}
cout << "Is a palindrome" << endl;
return 0;
}Palindrome String solution in c++
class Solution{
public:
int isPalindrome(string S)
{
// Your code goes here
int n=S.length();
for(int i=0;i<n/2;i++)
{
if(S[i]!=S[n-1-i])
{
return 0;
}
}
return 1;
}
