Solution: Kth Smallest Prime Fraction

Explore how to apply the K-way merge pattern to identify the kth smallest fraction from prime numbers in a sorted array. Understand the heap-based approach for merging fraction sequences, ensuring an efficient search with optimal time and space complexity.

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 ...
