Solution: Kth Smallest Prime Fraction

Explore a method to identify the kth smallest fraction formed by prime numbers in a sorted array by using a heap-based k-way merge approach. Understand how to efficiently manage fractions, update the heap, and achieve optimal time complexity while retrieving the correct numerator and denominator.

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 ...
