Solution: Kth Smallest Prime Fraction

Explore how to find the kth smallest fraction formed from a sorted array of unique prime numbers and 1. Learn to implement a heap-based k-way merge algorithm that iteratively processes fractions by numerator and denominator indices to extract the desired fraction efficiently. Understand the approach's time and space complexities and how it manages data using a min heap.

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 ...
