Convert the string into palindrome string by changing only one character in C++
In this tutorial, we will be discussing a program to convert the string into palindrome string by changing only one character.
For this we will be provided with a string. Our task is to convert the given string into a palindrome by changing only one character.
Example
#include<bits/stdc++.h>
using namespace std;
//checking if conversion to palindrome
//is possible
bool if_palindrome(string str){
int n = str.length();
//counting number of characters
//to be changed
int count = 0;
for (int i = 0; i < n/2; ++i)
if (str[i] != str[n - i - 1])
++count;
return (count <= 1);
}
int main(){
string str = "abccaa";
if (if_palindrome(str))
cout << "Yes" << endl;
else
cout << "No" << endl;
return 0;
}Output
Yes
