Introduction

In this blog post, we will explore how to solve the LeetCode problem "1317" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like Chatmagic, 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

No-Zero integer is a positive integer that does not contain any 0 in its decimal representation. Given an integer n, return a list of two integers [a, b] where: a and b are No-Zero integers. a + b = n The test cases are generated so that there is at least one valid solution. If there are many valid solutions, you can return any of them. Example 1: Input: n = 2 Output: [1,1] Explanation: Let a = 1 and b = 1. Both a and b are no-zero integers, and a + b = 2 = n. Example 2: Input: n = 11 Output: [2,9] Explanation: Let a = 2 and b = 9. Both a and b are no-zero integers, and a + b = 11 = n. Note that there are other valid answers as [8, 3] that can be accepted. Constraints: 2 <= n <= 104

Explanation

• Iterate from a = 1 up to n - 1.
  • For each a, check if both a and b = n - a are No-Zero integers.
  • If both are No-Zero, return [a, b].

• Runtime Complexity: O(n log n), Storage Complexity: O(1)
