palint

Palint, also known as a palindromic integer, is a number that reads the same backward as forward. For example, 121 is a palindint because if you reverse the digits, you get 121. Other examples include 5, 33, 1001, and 98789.

Palints are a common concept in recreational mathematics and computer science. They often appear in puzzles and programming challenges. The definition of a palindint is straightforward, but exploring properties of larger palindints can become more complex.

Single-digit numbers are always considered palindints as there is no reversal to perform. Two-digit palindints are those where both digits are the same, such as 11, 22, or 99. Three-digit palindints have the form ABA, where A and B are digits and A is not zero.

The study of palindints can extend to other number bases. For instance, in binary (base-2), the number 5 is represented as 101, which is also a palindint. The concept can also be applied to strings of characters, where a palindromic string reads the same forwards and backward, like "madam".

There are various algorithms to determine if a number is a palindint, typically involving reversing the digits of the number and comparing it to the original. These algorithms are frequently used in introductory programming exercises.
