How does X windows system launch a program?

Hello, I need some help to correct my algorithm steps to sum a number. I am confused... please input some steps
Example:
Let's say a number 5.
Now we can get a list of numbers: 1, 2, 3, 4 (less than 5 in sorted order).
so the sum could be: 1+4; 2+3 ( 1+1+1+1+1 or 1+2+2 is not a solution).

Hi I am trying to make my scripts to run from any directory and after some research (googling) I find there are 2 ways to do this

repodiff
repodiff(1)repodiff(1)NAME
repodiff - list differences between two or more Yum repositories
SYNOPSIS
repodiff --old=old_repo_baseurl --new=new_repo_baseurl
DESCRIPTION
repodiff is a program which will list differences between two sets of repositories. Note that by default only source packages are com-
pared.
GENERAL OPTIONS --old, -o
Add a repo. as an old repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and not a
baseurl.
--new, -n
Add a repo. as an new repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and not a
baseurl.
--archlist, -a
Add architectures to change the default from just comparing source packages. Note that if you want the same as a native "x86_64"
architecture machine you just need to pass "x86_64" (this is different from earlier versions where you needed to specify
"x86_64,athlon,i686,i586,i486,i386,noarch" and you still got "src").
--size, -s
Output additional data about the size of the changes.
--compare-arch
Normally packages are just compared based on their name, this flag makes the comparison also use the arch. So foo.i386 and
foo.x86_64 are different.
--simple
Output a simple one line message for modified packages.
--downgrade
Split the data for modified packages between upgraded and downgraded packages.
EXAMPLES
Compare source pkgs in two local repos:
repodiff --old=/tmp/repo-old --new=/tmp/repo-new
Compare x86_64 compat. binary pkgs in two remote repos, and two local one:
repodiff -a x86_64 --old=http://example.com/repo1-old --old=/tmp/repo-old --new=http://example.com/repo1-new --new=/tmp/repo-new
Compare x86_64 compat. binary pkgs, but also compare arch:
repodiff -a x86_64 --compare-arch --old=http://example.com/repo1-old --old=/tmp/repo-old --new=http://example.com/repo1-new
--new=/tmp/repo-new
Compare two releases of Fedora (15 => 16):
repodiff --old='mirror:https://mirrors.fedoraproject.org/metalink?repo=fedora-source-15&arch=i386' --new='mirror:https://mir-
rors.fedoraproject.org/metalink?repo=fedora-source-16&arch=i386' --size --simple --downgrade
