Understanding the Prime Pairs With Target Sum Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an integer n. We say that two integers x and y form a prime number pair if: 1 <= x <= y <= n x + y == n x and y are prime numbers Return the 2D sorted list of prime number pairs [xi, yi]. The list should be sorted in increasing order of xi. If there are no prime number pairs at all, return an empty array. Note: A prime number is a natural number greater than 1 with only two factors, itself and 1.

Examples
n = 10[[3,7],[5,5]]In this example, there are two prime pairs that satisfy the criteria. These pairs are [3,7] and [5,5], and we return them in the sorted order as described in the problem statement.
n = 2[]We can show that there is no prime number pair that gives a sum of 2, so we return an empty array.
