Coding question here. Please explain your thought process, thank you.
**Palindrome Number** Given an integer \( x \), return `true` if \( x \) is a palindrome, and `false` otherwise. ### Example 1: - **Input:** \( x = 121 \) - **Output:** `true` - **Explanation:** 121 reads as 121 from left to right and from right to left. ### Example 2: - **Input:** \( x = -121 \) - **Output:** `false` - **Explanation:** From left to right, it reads -121. From right to left, it becomes 121-. Therefore, it is not a palindrome. ### Example 3: - **Input:** \( x = 10 \) - **Output:** `false` - **Explanation:** Reads 01 from right to left. Therefore, it is not a palindrome. On the right side of the screen, a code editor is open with a scaffold for a Python function: ```python def solution(num): # your solution goes here ``` Below the code editor, there is an interactive terminal section.
