Program to Find the nth Palindrome Number

 Palindrome Number: remains the same when it's reverse the digits.

Example:
               212
               717
              
Problem statement:-  Program to Find the nth Palindrome Number.

Data requirement:-

   Input Data:- rangenumber

   Output Data:- rangenumber, letest

   Additional Data:- c, num, num1, sum, rem, num2

Program in C

Here is the source code of the C Program to Find the nth Palindrome Number.

Code:

//Write a program to find the nth palindrome number.
#include <stdio.h>
int
main ()
{
  int i, rangenumber, num = 1, c = 0, latest = 0;
  printf ("Enter the Nth value:");
  scanf ("%d", &rangenumber);

  while (c != rangenumber)
    {
      int num1=num;
      int num2=0;
    while(num1!=0)
    {
        int rem=num1%10;
        num1/=10;
        num2=num2*10+rem;
    }
    if(num==num2)
      {
          c++;
          latest=num;
      }
      num = num + 1;
    }
  printf ("%dth palindrome number is %d", rangenumber, latest);
  return 0;
}

Input/Output:

Enter the Nth value:15
15th palindrome number is 66

Program in C++

Here is the source code of the C++ Program to Find the nth Palindrome Number.

Code:

#include <iostream>
using namespace std;
int
main ()
{
  int i, rangenumber, num = 1, c = 0, latest = 0;
  cout<<"Enter the Nth value:";
  cin>>rangenumber;

  while (c != rangenumber)
    {
      int num1=num;
      int num2=0;
      //reverse of number
    while(num1!=0)
    {
        int rem=num1%10;
        num1/=10;
        num2=num2*10+rem;
    }
    if(num==num2)
      {
          c++;
          latest=num;
      }
      num = num + 1;
    }
  cout<<rangenumber<<"th palindrome number is "<<latest;
  return 0;
}

Input/Output:

Enter the Nth value:19
19th palindrome number is 101

Program in Java

  

Here is the source code of the Java Program to Find the nth Palindrome Number.

Code:

import java.util.Scanner;
public class NthPalindromeNumber {

public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
int  rangenumber, num = 1, c = 0, latest = 0;
  System.out.println("Enter Nth number:");
  rangenumber=cs.nextInt();

  while (c != rangenumber)
    {
  int num1=num;
      int num2=0;
    while(num1!=0)
    {
        int rem=num1%10;
        num1/=10;
        num2=num2*10+rem;
    }
    if(num==num2)
      {
          c++;
          latest=num;
      }
      num = num + 1;
    }
 System.out.println(rangenumber+"th Palindrome Number is "+latest);
cs.close();
}
}

Input/Output:

Enter Nth number:
23
23rd Palindrome Number is 141

Program in Python
  

Here is the source code of the Python Program to Find the nth Palindrome Number.

Code:

rangenumber=int(input("Enter a Nth Number:"))
c = 0
latest = 0
num = 1
while c != rangenumber:
    num2=0
    num1 = num
    while num1 != 0:
        rem = num1 % 10
        num1 //= 10
        num2 = num2 * 10 + rem
    if num==num2:
        c+=1
        latest = num

    num = num + 1
print(rangenumber,"th Palindrome Number is ",latest)

Input/Output:

Enter an Nth Number:16
16 th Palindrome number is  77
