Solution: Kth Smallest Prime Fraction

Understand the method to find the kth smallest prime fraction by applying a k-way merge strategy. This lesson guides you through heap operations to systematically extract fractions in ascending order, optimizing time and space complexity for interview problems.

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 ...
