K’th Largest Item

August 1, 2014

Today’s exercise is a common interview question, and also interesting in its own right:

Find the kth largest integer in a file of n integers, where n is large (defined as too large to fit into memory all at once) and k is small (defined as small enough to all fit in memory).

Your task is to write the program described above. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
