Solution: Kth Smallest Prime Fraction

Explore how to determine the kth smallest fraction formed by elements in a sorted array of unique primes using a k-way merge algorithm. This lesson teaches implementing a min-heap to track and generate candidate fractions, ensuring efficient extraction of the desired fraction while balancing time and space complexity.

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 0i<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 ...
