# Solving Leetcode Interviews in Seconds with AI: Strictly Palindromic Number


	# Introduction
	In this blog post, we will explore how to solve the LeetCode problem "2396" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like [Chatmagic](https://www.chatmagic.app), we can generate solutions quickly and efficiently - helping you pass the interviews and get the job offer without having to study for months.

	# Problem Statement
	> An integer n is strictly palindromic if, for every base b between 2 and n - 2 (inclusive), the string representation of the integer n in base b is palindromic. Given an integer n, return true if n is strictly palindromic and false otherwise. A string is palindromic if it reads the same forward and backward.   Example 1:  Input: n = 9 Output: false Explanation: In base 2: 9 = 1001 (base 2), which is palindromic. In base 3: 9 = 100 (base 3), which is not palindromic. Therefore, 9 is not strictly palindromic so we return false. Note that in bases 4, 5, 6, and 7, n = 9 is also not palindromic.  Example 2:  Input: n = 4 Output: false Explanation: We only consider base 2: 4 = 100 (base 2), which is not palindromic. Therefore, we return false.     Constraints:  4 <= n <= 105  

	# Explanation
	Here's a breakdown of the solution:

*   **Recognize the Pattern:** The key observation is that no number `n` can be strictly palindromic for `n > 3`. This is because in base `n-1`, `n` is always represented as `11`. Therefore, we only need to check if `n` is greater than 3.
*   **Direct Return:** If `n` is greater than 3, we immediately return `False`. Otherwise, it satisfies the condition.

*   **Runtime Complexity:** O(1), **Storage Complexity:** O(1)

    """
    Given an integer n, return true if n is strictly palindromic and false otherwise.

    A string is palindromic if it reads the same forward and backward.

    Example 1:
    Input: n = 9
    Output: false
    Explanation:
    In base 2: 9 = 1001 (base 2), which is palindromic.
    In base 3: 9 = 100 (base 3), which is not palindromic.
    Therefore, 9 is not strictly palindromic so we return false.
    Note that in bases 4, 5, 6, and 7, n = 9 is also not palindromic.

    Example 2:
    Input: n = 4
    Output: false
    Explanation:
    We only consider base 2: 4 = 100 (base 2), which is not palindromic.
    Therefore, we return false.

    Constraints:
    4 <= n <= 105
    """
    return False
