Solution: Kth Smallest Prime Fraction

Explore the solution to finding the kth smallest prime fraction in a sorted array by using a min-heap to efficiently merge fractions. Understand how to process fractions by numerator and denominator indices and manage heap operations to identify the desired fraction. This lesson helps you implement and analyze the time and space complexities of the approach, enhancing your coding interview problem-solving skills.

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 ...
