MAX_CNT

#define MAX_CNT   4096

Test program for sorting and searching in lib/stdlib.c.

Attempts to test the sorting and searching functionality that is not sufficiently tested elsewhere in Pintos.

This is not a test we will run on your submitted projects. It is here for completeness. Maximum number of elements in an array that we will test.
