[interviewDojo] #2: Merge K sorted array, size N each

Hi,

Today we solve a classic sorting problem that is full of great patterns and ideas (super useful to solve interview problems).

Problem
Given K sorted arrays, write an algorithm that merges these arrays and returns a single sorted array.

Example:

Input:

{{1, 3, 4}, {5, 6, 11}, {2, 9, 10}}

Output:

{1, 2, 3, 4, 5, 6, 9, 10, 11}

Solution
Try to solve the problem by yourself and then go over our discussion and solution to learn more.
