Mathematical Concepts

What is a Palindrome?

A palindrome is a number that reads the same forwards and backwards. In mathematical terms, a number n is a palindrome if:

n = reverse(n)

Where reverse(n) is the number formed by reversing the digits of n.

Palindrome Properties

Palindromic numbers have several interesting mathematical properties:

• Symmetry: The number is symmetric around its center
• Length Parity: Can be odd or even length
• Digit Patterns: Follow specific patterns based on length
• Frequency: Become less common as length increases

Generation Algorithms

Custom Number Method

When generating from a custom number, the algorithm:

1. Analyzes Input: Takes your input number as a base
2. Creates Mirror: Generates palindromes by mirroring digits
3. Handles Length: Adjusts for different target lengths
4. Validates Results: Ensures all generated numbers are palindromes

Random Generation Method

For random palindromes, the algorithm:

1. Selects Length: Randomly chooses a length within the specified range
2. Generates Half: Creates the first half of the palindrome
3. Mirrors Digits: Creates the second half by reversing the first half
4. Handles Middle: For odd lengths, adds a middle digit

Range Search Method

For systematic search, the algorithm:

1. Defines Range: Sets the search range based on length parameters
2. Iterates Numbers: Checks each number in the range
3. Tests Palindrome: Verifies if each number is a palindrome
4. Collects Results: Gathers all palindromes found

Palindrome Examples

Single Digit Palindromes

Two Digit Palindromes

Three Digit Palindromes

Four Digit Palindromes

Mathematical Patterns

Odd Length Palindromes

For odd-length palindromes, the pattern is:

abc...cba where the middle digit can be any digit 0-9

Even Length Palindromes

For even-length palindromes, the pattern is:

abc...cba where the number is perfectly mirrored

Counting Palindromes

The number of palindromes of length n is:

• Odd length n: 9 × 10^((n-1)/2)
• Even length n: 9 × 10^(n/2-1)
