Algorithms are mathematical descriptions of solving
a problem. Algorithms can be illustrated in pseudo code
and proved using algebra and discrete mathematics.
It is important not to confuse between an algorithm
and its implementation in a programming language.
It is true that some languages are more suited to
solving problems in a certain way, than others. Due
to the language elements supported by different
languages, solutions might vary.
For example, many things can be done in C++ templates,
for which you may not be able draw parallels in other languages.
A lisp algorithm might look more "elegant" in the eyes
of a Lisper than anything else. A Pythonista might swear
for the beauty of his code over similar C/C++ code.
These are just variations in viewpoint and don't
illustrate anything fundamentally different between the
Programming languages are tools to solve problems.
Most often, a language might be more suitable to the
problem at hand than other ones. This is often determined
by things like time & cost constraints, skill availability,
freely available software in that language, performance
considerations etc than any perceived superiority of
I never understood language wars. Got a programming
language you love, good. But such comparisons are frankly
a waste of time...
