Palindrome number

Detailed guide and Python implementation for the 'Palindrome number' problem.

問題提起

簡単

Write a function is_palindrome(n) that takes a non-negative integer n and returns True if n reads the same forwards and backwards, or False otherwise.

制約
  • 0 <= n <= 10^9

Example 1
Input
n = 121
Output
True
Explanation

121 reversed is 121, which is the same, so it is a palindrome.

Example 2
Input
n = 123
Output
False
Explanation

123 reversed is 321, which is different, so it is not a palindrome.

Example 3
Input
n = 0
Output
True
Explanation

0 reversed is 0, so it is a palindrome.

Need a Hint?
Consider using Basics-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
