In this Python Program, we will learn how to print Palindrome Numbers from 1 to 100 or between a specific range.
What is Palindrome?
A palindrome is a word, number, phrase, or other sequences of characters that reads the same backward as forward, such as civic or rotator or the number 14241.
A number is a palindrome when we reverse the number and the reversed number is equal to the original number.
Here is the code of the program to print Palindrome Numbers from 1 to 100 or between a specific range.
# Python Program to print Palindrome numbers from 1 to 100
# Take the Input from the User
minValue = int[input["Enter the Minimum Value : "]]
maxValue = int[input["Enter the Maximum Value : "]]
print["Palindrome Numbers between %d and %d are : " %[minValue, maxValue]]
for num in range[minValue, maxValue + 1]:
temp = num
reverse = 0
while[temp > 0]:
Reminder = temp % 10
reverse = [reverse * 10] + Reminder
temp = temp //10
if[num == reverse]:
print["%d " %num, end = ' ']
Enter the Minimum Value : 1
Enter the Maximum Value : 100
Palindrome Numbers between 1 and 100 are :
1 2 3 4 5 6 7 8 9 11 22 33 44 55 66 77 88 99

Given a range of numbers, print all palindromes in the given range. For example if the given range is {10, 115}, then output should be {11, 22, 33,
44, 55, 66, 77, 88, 99, 101, 111}
We can run a loop from min to max and check every number for palindrome. If the number is a palindrome, we can simply print it.
Implementation:
C++
#include
using namespace std;
int isPalindrome[int n]
{
int rev = 0;
for [int i = n; i > 0; i /= 10]
rev = rev*10 + i%10;
return [n==rev];
}
void countPal[int min, int max]
{
for [int i = min; i None:
for i in range[minn, maxx + 1]:
if isPalindrome[i]:
print[i, end = " "]
if __name__ == "__main__":
countPal[100, 2000]
C#
using System;
class GFG
{
public static int isPalindrome[int n]
{
int rev = 0;
for [int i = n; i > 0; i /= 10]
{
rev = rev * 10 + i % 10;
}
return [n == rev] ? 1 : 0;
}
public static void countPal[int min,
int max]
{
for
[int i = min; i 0; i /= 10]
{
rev = [[rev*10] + [Math.trunc[i]%10]];
}
return [n==rev];
}
function countPal[min, max]
{
for [var i = min; i 0]: dig=n%10 rev=rev*10+dig n=n//10 if[temp==rev]: print["The number is a palindrome!"] else: print["The number isn't a palindrome!"]
