What 5 letter word typed in all capital letters can be read the same upside down? Answer: SWIMS.

Friday backwards: The word Friday spelled backward is yadirf which is not a word.

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 term palindromic is derived from palindrome, which refers to a word (such as rotor or racecar) whose spelling is unchanged when its letters are reversed.

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).

How to check if a number is palindrome

1. Declare two variables: one stores the given number, and the other stores the reversed number.
2. Run the do-while loop until the number of digits in the reversed number are equal to the number of digits in the given number.
3. Check if the reversed number is equal to the given number.

According to the Farmers’ Almanac, 2021 will have a total of 22 palindrome dates, which are dates that read the same forwards and backward in four, five, and six-digit formats. “The only two years in a century that contain 22 palindrome dates are the ones ending with 11 and 21,” Dr. Inan said.

Some cultures believe palindrome dates to be lucky. Which is why many people choose these dates for wedding celebrations. It also looks attractive to have the unique pattern of numbers appear on an invitation that’s a lifetime keepsake; dates such as 02.02. 2020 or were very popular dates for nuptials!

“The only two years in a century that contain 22 palindrome dates are the ones ending with 11 and 21,” Dr. Aziz Inan, an electrical engineering professor at the University of Portland, said, according to the Farmers’ Almanac. “The year 2011 had 22, and in the next century, they will be found in 2111 and 2121.”

Palindromic dates are considered lucky in several cultures, although much depends on the date-writing convention. A big day in America, which puts the month before the day, is rarely the same as a big day in Britain, where the day usually goes before the month.

By Aparna Kher. Palindrome Days happen when the day’s date can be read the same way backward and forward. The dates are similar to word palindromes in that they are symmetrical. ‘BOB’ is a palindrome.

Answer: YES, so that means the number 222 is a palindrome!

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 8,188. 10,911 reaches the palindrome (28 digits) after 55 steps.

8.2. 6 The Palindrome-Number Problem

1. Generate a consistent list of candidate numbers that might solve the problem.
2. Square the number.
3. Convert the squared number into a string (e.g., convert the integer 123 into the string “123”) and then use string operations to see if the candidate satisfies the three requirements.

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 If you take the front half (“prefix”) of the number, i.e. 1234, you can use that to estimate the number of palindromes.
