A palindromic number is a number (in some base ) that is the same when written forwards or backwards, i.e., of the form.


The first few palindromic numbers are therefore are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, …

(OEIS A002113)..

Is C++ a palindrome?

This program takes an integer from user and that integer is reversed. … If the reversed integer is equal to the integer entered by user then, that number is a palindrome if not that number is not a palindrome.

Is Python a palindrome?

Explanation: In the above program, first take input from the user (using input OR raw_input() method) to check for palindrome. Then using slice operation [start:end:step], check whether the string is reversed or not. Here, step value of -1 reverses a string. If yes, it prints a palindrome else, not a palindrome.

What is a special number?

Special Numbers in Java are ones whose sum of factorials of digits is equal to the number itself. It can be an N digit number. The program has to first break the number into its corresponding digits and calculate their factorials. … If the sum matches the original number then the number is called to be a Special number.

Is 69 a palindrome?

Answer: NO, so that means the number 69 is not a palindrome!

What is palindrome number example?

A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16461) that remains the same when its digits are reversed. … The palindromic primes are 2, 3, 5, 7, 11, 101, 131, 151, … (sequence A002385 in the OEIS).

What is a palindrome of 89?

89 takes an unusually large 24 iterations (the most of any number under 10,000 that is known to resolve into a palindrome) to reach the palindrome 8,813,200,023,188. 10,911 reaches the palindrome 4668731596684224866951378664 (28 digits) after 55 steps.

Is 2020 a palindrome?

Sunday – 02/02/2020 – is the first “global” palindrome since 11/11/1111. Unlike other palindromic dates, such as 10/02/2001, 2 February, 2020 is considered a global palindrome because it is exactly the same written both in the DD/MM/YYYY format as well as the US standard of MM/DD/YYYY.

How do you find the palindrome between two numbers?

You can just look at the front half of the given number to get an estimate of the number of palindromes. How many palindromes are there between 1 and 12345678? If you take the front half (“prefix”) of the number, i.e. 1234, you can use that to estimate the number of palindromes.

What is the most beautiful number?

1.6181.618. The so-called Golden Number or phi defines a ratio that appears repeatedly in nature, for example in the way many flowers’ petals are formed. Some claim it is also associated with beauty, although leading mathematicians insist this is not true.

Is a single digit a palindrome?

All single digits are considered palindromes in a base 10 system: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Two digit palindromes are also easy to find. … Furthermore, for any k digit palindrome, the middle digit (for Page 4 3 an odd number of digits) or the middle two (for an even number of digits) must also be the same.
