Solution: Kth Smallest Prime Fraction

Explore how to find the kth smallest fraction formed by pairs of prime numbers in a sorted array using the K-way merge pattern. This lesson guides you through implementing a heap-based solution that efficiently manages fractions and ensures optimal time and space complexity. Understand how to iterate through fractions systematically to retrieve the kth smallest with clear algorithmic steps and complexity analysis.

We'll cover the following...

Statement

You are given a sorted array of unique integers, arr, which includes the number 11 and other prime numbers. You are also given an integer kk.

For every index ii and jj where 0≤i<j<0 \leq i < j < arr.length, you can form a fraction by taking the number at index ii as the numerator and the number at index jj ...
