We're really not supposed to help folks with homework assignments on this board. But you've done most of the work and you're stuck on a very tricky problem.

if [ -n $x ]

will not work, If there is nothing in x the command becomes:

if [ -n ]

So you need to use

if [ -n "$x" ]

Now when threre's nothing in x, the command becomes

if [ -n "" ]

NAME
freecell-solver-range-parallel-solve - The Freecell Solver utility for solving a range of Microsoft Freecell/Freecell Pro Boards SYNOPSIS
freecell-solver-range-parallel-solve start end print_step [--binary-output-to filename] [--total-iterations-limit limit] [fc-solve Arguments...] DESCRIPTION
freecell-solver-range-parallel-solve is a command line application that solves a range of Freecell deals of Microsoft Freecell and Freecell Pro. start is the first board to solve; end is the last (inclusive) and print_step is the division of board numbers in which to print a status message. Following this three mandatory parameters are several flags specific to the range solve. (refer to the OPTIONS section for more information) Afterwards one can give it a fc-solve command line that it will use to solve each board. Refer to the fc-solve(6) man page for information about its options. OPTIONS
--total-iterations-limit sets the maximal number of iterations with which to try to solve each deal. After that, the program will give up and report that the board was intractable. --binary-output-to sets the filename into which to output the number of iterations it took to solve each board. This file can later be used with statistical preset optimizers such as those found in the Freecell Solver version control repository. SEE ALSO
