Solution: Kth Smallest Prime Fraction

Explore how to identify the kth smallest fraction formed from a sorted array of prime numbers and 1 by using a min heap and k-way merge strategy. Understand the algorithm that efficiently manages fractions as pairs, its time and space complexity, and how it tackles this prime fraction problem.

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 ...
